Department of Defense Now Blocking HTML Email

oKAMi-InfoSec writes "The Department of Defense (DoD) has taken the step of blocking HTML-based email. They are also banning the use of Outlook Web Access email clients. The DoD is making this move because HTML messages can easily be infected with spyware and executable lines of code that enable hackers to access DoD networks, according to an article in Federal Computer Week by Bob Brewin . A spokesman for the Joint Task Force for Global Network Operations (JTF-GNO) claims that this is a response to an increased network threat condition. The network threat condition has risen from Information Condition 5 to Information Condition 4 (also called Infocon 4). InfoCon 5 is normal operating conditions and Infocon 4 comes as a result of 'continuing and sophisticated threats' against DoD Networks. The change to Infocon 4 came in mid-November, after the Naval War College suffered devastating attacks that required their entire system be taken offline, but the JTF-GNO spokesman claims there is no connection."

That aside, I wonder how many products the military already uses send HTML email. Not all email originates from ordinary mail clients.....

Re:Good call

I for one certainly don't miss the annoying pink backgrounds and purple text. But, you forget that a lot of internet based applications send out emails. So you should really include the developers in the losers category here.

I don't know how many email templates I've gone though in the past week converting them to be plain text (where necessary). This mainly applies to processes that include sending tabular data to a person.

which raises the question: why don't they just strip html out instead? it will probably require more work to make sure nothing gets through, but i think that it might be worth it.

Re:Good call

[shadowmas]

This is very true. I my self personally prefer plain text mail except when using outlook at the office where i use the default html or richtext.

however when developing i do sometimes use html because it makes reading tabular data and such much easier to read at a glance. true you could use plain text for these but with lots of information it makes it difficult to quickly extract the information you need.

Re:Good call

[leamanc]

I actually prefer my tabular data emails in plain text. Just include the good old disclaimer "This message is best viewed in a fixed-width font like Monaco or Courier."

I find it easier to copy-n-paste into Excel or a text editor when it's plain tabbed text, rather than an HTML table.

Just my $0.02, not adjusted for inflation.

Re:Good call

[1u3hr]

which raises the question: why don't they just strip html out instead?

They do. "A Navy user said that any HTML messages sent to his account are automatically converted to plain text." But if you've used tables or such the layout will probably be trashed, so better to reformat as plain text to begin with.

Using something like Lynx to filter HTML into plain text would give pretty good results, it does tables fairly well.

Re:Good call

[World_Leader]

which raises the question: why don't they just strip html out instead? it will probably require more work to make sure nothing gets through, but i think that it might be worth it.

Wouldn't any attempt to strip html and leave something intelligible open the possibility of infecting the "stripping" machine?

If they had confidence they could do that they could probably just convert the mail to an image (ok, losing active elements such as links and input fields) and send it as a simple encoded/mime image.

But it's really the same problem moved one step away, which admittedly could be better controlled. Maybe, e.g., lynx -dump but I can see where their analysts might ask exactly how they convince themselves that would remove every possible new threat posed by running it thru a stripper.

I bet they've also been told 1000x that what they were using to view email is now fixed and safe (hah!) This is, if anything, an understandable cry of pain and frustration.

Re:Good call

[cluckshot]

If you are DOD and you want to get Commercial Off the Shelf (COTS) products to resolve your problems without hiring the massively expensive solutions of 1 off stuff built to design, you must be able to accept attachments such as .zip and html mail. Sorry but the commercial guys cannot even tell you what they are doing anymore without this stuff. DOD costs just got higher!

I worked one DOD site where we had to email files of code. The volume of the attachments was beyond the Email limits so we had to zip the files. The filters blocked .zip. So we renamed the files .aaa or something like that. Then the filters didn't catch the files. That way we could get the emails. We had to break our own security just to do our job. This stuff is a real problem.

The US DOD needs to can Microsoft. If they were to run Linux or Apple systems and then to sandbox all emails and web browser stuff under the OS a lot could be done and things would be much more secure. The basic problem is a Microsoft logical design construct. Microsoft thought that they should own your computer and you should rent it from them. Under these conditions they wanted "their" computers to be remotely controlled by various means. The means they designed into their constructs also leave sucking security holes which hackers and other malware designers just walk right through.

There is a real reason most DOD people stick like glue to Microsoft. For Network security people in the DOD they are as worried that some subordinate might actually control his machine as they are of having foreign control. (Foreign to their system) As such they must keep central control. This is the Microsoft construct at a second level. The DOD system I worked on had an entire base having one root password that didn't change folks because of this demand. Linux etc doesn't conform to this as naturally as MS systems. Another level of this sticking like glue to MS systems comes from the fact that most of the people who program (contractors etc) for the Government like to keep their jobs. MS systems do not support legacy software well. As such they are continually "re-inventing the wheel" so to speak and it makes for lots of jobs that last a lifetime. It holds the DOD hostage to continually hiring the same contractor because his software is proprietary and cannot be easily "reverse engineered" without risk of software copyright violations. In the end this synergy of profits and control leaves the US DOD bleeding money, never able to do its job as effectively and wedded to MS systems.

If the taxpayers get involved they will ban such OS like Microsoft because this is completely contrary to the interest of the taxpayers. It however; requires the US DOD to recognize that its only true security lies in the loyalty of its people. In doing so it will have to retract from foreign (non-USA) suppliers and contractors. It will have to seriously look into who it is hiring and it will have to weed out those it has on payroll who are being more selfish than loyal. Let me assure you that if this situation is dealt with properly it will be a top to bottom 10 on the Richter Scale earthquake in US Government operations. Imagine if you will actually not being able to have the management read every document in someones computer without them knowing. Imagine having someone who works for you who you actually have to be able to trust! Imagine real government security! (WOW!)

Re:Good call

[shadowmas]

true enough and usually you don't even need to change the font since most clients show plain text with courier.

however there are status and summary messages sent by the system which is preferable to be read without going into excel or third party app. of course if you have a large amount of tabular data it's much better to generate a CSV formatted attachment which is more convenient. but for a relatively little amount of data which needs to be looked at quickly html tables are the best.

Re:Good call

[partenon]

If the taxpayers get involved they will ban such OS like Microsoft because this is completely contrary to the interest of the taxpayers. Agree. DoD should use the same OS as the taxpayers.

The problem isn't w/ Microsoft itself. Ok, they produce crappy programs, but the main problem is w/ *people* who use it. If people inside DoD can't get the basics of internet defense themselves, it's their fault. They aren't like my grandma who can't use Windows for 5 minutes w/out getting tons of spywares. They are supposed to know at least the basics of internet defense. Don't open executable files, prefer plain text instead of HTML mails, don't click 'OK' w/out reading the actual message, don't trust on every site on internet, ...

And just one more thing: instead of using ZIP files w/ "aaa" extension, why don't they build a simple web application to promote the file exchange, making it easier, safer and more auditable than emails (which aren't supposed to be used as file exchange media)?

Re:Good call

[partenon]

This mainly applies to processes that include sending tabular data to a person. Emails aren't supposed to display tabular data :-) Emails are for "internet messages". If you want someone to actually read tabular data, send a link to the tabular data file (a spreadsheet?).

Re:Good call

[haakondahl]

I agree, but you seem to have overlooked that with a non-MS OS, you can actually have better security while still employing people you may not trust. There is no reason that the workstation desktop user needs to have advanced permissions, particularly if the workstation exists as a glorified terminal. With humble user permissions on the workstation, the information worker can do whatever needs to be done locally, and still has access to tightly controlled and centrally located user areas (mailbox, storage) and share areas (shared storage, collaborative space).

This is all possible in theory under MS, but in practice, by the time you have security, you have too little ability. In UNIX/Linux shops, security can be had while preserving the ability to get things done.

I look forward to the day that the government internalizes its own security, instead of this hand-in-glove approach which leaves government beholden to MS. Yay, G-buntu!

Re:Good call

[PastaLover]

Best practice would be to have a plaintext version of any html mail you send out so you can send them both as parts to the same mail. Any reasonable graphical mail client will show you the html version and text clients will default to the plaintext version. This makes your mail more accessible (in terms of screenreaders and unix fossils), gives you a wider audience and scores you brownie points with the geek crowd. No reason not to do it I'd say.

Only bad developers lose out on this one.

You should be aware that there has been such a format for quite a while, using the MIME type of text/enriched. I used to receive quite a few emails that used it (no, I don't remember what the originating client was and I'm not interested in looking it up right now) but it never seemed to catch on more widely. (At a wild guess, that's because Outlook didn't generate it; yet another opportunity missed by those geniuses at Microsoft...)

Personally, I'd find that annoying, like every other attempt to be interesting, or creative or otherwise expressive. Look folks, many of us read hundreds of emails per day. Subscribing to few mailing lists and we're looking at thousands.

Do we really need or want anything other than standard messages? The content of an average message is just a few sentences. What people send out, on the other hand, is somewhere between unecessary and absurd. And all of it (at least in a corporate setting) gets stored and archived.

Re:As They Should

I don't know how old you are, but I'm still a college student and I share your feelings as well. What annoys me the worst is that retarted mail client called Outlook that has a love afair with <FONT SIZE=8 COLOR=BLUE> [1]. Text is wonderful because it allows me to specify the color, font family, and size of the email so I can read the blasted thing.

Plain text isn't perfect either. Things like text formating is often done in awkward ways that can get screwed up fairly easily. (The 80 column line wrapping thing is the biggest offender.

Personally, I think that another system, maybe a strictly designed subset of XHTML or Restructured Text (for XML haters), needs to be designed. It should only contain semantic elements. No style or scripting capabilities at all.

[1] I'm not sure if that's the actual markup it uses. It's an educated guess based on Microsoft's other tools. It's been trimmed a bit for readablity. The real version whould have all sorts of MS Office specifice attributes with magical namespaces floating around (and HTML doesn't even have namespaces, go figure).

ARGH! I know exactly what you mean. I used to work at a mostly MS-dominated company, full of people using Outhouse and MSexchange, and most e-mails would have those defaults, which would appear at an annoyingly small size under the OS X mail program. I always had to just give up and hit the command keys to show them as plain text. Having a mail program specify the font size BY DEFAULT in HTML mail is completely and thoroughly brain damaged, doubly so when the default is so small.

And there's a small amount of blame to be directed at Apple as well, for not providing any way to either override or ignore such brain-damaged defaults.

Re:As They Should

There is (was) a "rich text" for email, looked like a subset of HTML. It was used by early versions of Eudora and other mail clients. I think we can blame Netscape for putting HTML into email, and this was cemented when Outlook came along and started doing it by default. All the other mail clients had to follow though they knew it was a Bad Idea.

Losing HTML doesn't mean you lose the ability to have email attachments. MIME should still work in the absence of HTML.

But just for fun, you could return to the classics and UUENCODE it.

Its been a while, but circa 1997 Microsoft Exchange used to automatically change a UUENCODed section in an email into an attachment. (Or maybe it was Outlook that did it.) Anyway, it happened automagically. It was pretty useful for doing automatic archives via email from a linux system.

Better yet, just pitch all the email......

[banerjek]

At least then people will know why their email never got through. So many people use HTML email without being aware of it and don't realize that's what makes formatting possible.

Although the focus is on Outlook, it seems like there's an outside chance there may be other clients and web interfaces (namely all of them) that are vulnerable to most of the same problems....

Re:Better yet, just pitch all the email......

[Sepodati]

It still makes it through, it's just converted to plain text according to the article.

---John Holmes...

Re:Better yet, just pitch all the email......

[jark]

The email is not *converted* to plain text at all. There is absolutely no true format converting taking place at all.

By way of a Windows GPO the ability to compose email in HTML format is completely disabled. The default format for Outlook has been set to "Rich Text" so that people are still able to use a small subset of formatting. Users are capable of composing in plain text, but most will stick with the default.

Additionally, the Outlook preview pane is set to "convert" all inbound email to plain text. However, that does not do any actual converting of the original email therefore any digital signature remains intact. All that the preview pane "conversion" does is modify how the email is displayed, and nothing more.

Lastly, OWA is authorized for use so long as it is protected by two-factor CAC-based authentication. It is not summarily denied.

Most of the steps outlined in the article are best practices that should be used all the time, but for one reason or another are not implemented by the DoD on a regular basis.

Stupid

[Nicopa]

That's stupid. The problem is not with HTML mail (which is generated by many people unknowingly). They could just standarize in a safe mail program, with some mandatory defaults. They could force the use of a modified version of Thunderbird forcing the (already existing) oprion of "Disable JavaScript" off. Another interesting Thunderbird feature is the ability to "sanitize HTML", that is, remove from the HTML view anything that isn't strictly formatting (paragraphs, bullet lists, etc.).

Re:Stupid

[Beryllium Sphere(tm)]

But even without Javascript there are still web bugs, image file parsing exploits, and remember what engine is probably parsing the HTML on a Windows client. A "safe" email client is one that disables most of the features of HTML, and unless it's guaranteed to catch everything dangerous then it's safer to prevent HTML in the first place.

Up-to-date patches would mitigate those, but do you think somebody might be saving some zero-days for the DoD?

Re:Stupid

[Stumbles]

No, it's not stupid.... doing nothing is stupid. The simple fact remains. No matter what client your using, be it proprietary or some open source variety all the nastiest that can be placed in HTML is simply a hassle to block. Sure you can run things like spamassassin, razor and any number of things but those are just extra things that have to be maintained, updated, etc. The simplest is to dump HTML altogether. I have never been a fan of HTML email because it's a colossal waste of bandwith.

One question about Outlook that now would be a good time to ask:

Kind of like the difference between a multiline Text box, and a RichText control.

Re:Stupid

[Metshrine]

Thunderbird is a better solution here? I dont think so. People bad mouth outlook/exchange all the time, especially on /., however, in the case of most large enterprises (DoD especially), t-bird simply doesnt fit the bill. Outlook/Exchange offer so many more features and functions that most larger businesses and corporations use that t-bird doesnt even begin to fit into the same realm.

Do you honestly think the DoD is going to move from a platform which supports every feature they currently utilize (I know, I am in the US Army) to one which doesnt have support for basic things like calendaring, public folders, centralized rules administration, and various other features that simply arent available in this "better solution"? Thunderbird is not ready for the enterprise, nor will it be anytime soon without support for exchange/domino connectivity.

I am all for using open source, but when it doesnt fit the bill, I am not afraid to say that it wont do the job. Thunderbird is good for home use, but for corporate use (especially in a large entity like the DoD), its just sub-standard and lacking in the necessary areas. The fact of the matter is that you cant even access an exchange server with T-Bird.

Re:Stupid

[drmerope]

No. Its the KISS principle. Code complexity itself endangers security.

Rendering engines aren't rewritten frequently. Typically the code you have available for reuse supports many features you don't want: embedding, javascript, images (don't forget the GDI exploit). It is true that you can provide knobs to disable these dangerous features in the rendering engine. *BUT* have you ever been involved in real software verification efforts? Too many knobs means too little coverage.

Writing good tests is hard.

I have to assume that the DoD peformed some sort of balancing test: do the benefits of html exceed the risks?

People in general should ask themselves: do the benefits of pretty emails make up for the risk of having my computer rooted or leading to disclosure of personal information.

It is true, we could have both if enough people were willing to _pay_ lots of money for their rendering engine. It doesn't seem that is the case.

Re:Stupid

[@madeus]

I quite agree. I am typically not in favour of reducing functionality for increased security when there are viable alternatives, but disabling HTML email seems like a smart move in this case. It's simple and unlikely to be really inconvenient and it's had numerous problems for ages, I'm more a bit surprised they are only doing this now (personally I would have started with it off in an environment like the DoD).

While its true that many users unwittingly generate HTML email, pretty much all clients that do generate plain text versions too (using MIME/multipart) - it's easy to configure a mail server just to strip the HTML parts (not sure about Exchange, but certainly with something like Exim). Of course if Microsoft took a better approach to handling potential issues like this (by handling HTML messages better by default), I don't think anyone would have even seen HTML formatted messages as a risk (though they'd still be inconvinent in some other scenarios).

Re:Stupid

[dkf]

basic things like calendaring, public folders, centralized rules administration

I know what calendaring does (and note that there are free alternatives to Outlook under development) but what are "public folders" and "centralized rules administration"? Are public folders like an NNTP server, possibly with server-local or domain-local groups, which Thunderbird handles excellently? (Googling for "centralized rules administration" doesn't seem to lead to much enlightenment; too many other probably-unrelated schemes for centralizing the administration of rules in specific domains...) Without knowing exactly what features (at the technical level) are missing, it's hard to argue against what you say.

The fact of the matter is that you cant even access an exchange server with T-Bird.

That's one I know about, and it's because of the nasty mess that is Exchange, and especially its protocols for talking to Outlook. I could say more on what I think about this particular area, but it's the season of Goodwill To Men, so I think I prefer to stay mellow...

First, I didnt claim to have all the answers nor will I ever, however I do know that the army uses outlook to its potential and I know for a fact that thunderbird would not suite the needs of the army. Just because most of these tbird users dont like outlook and hate anything microsoft on principle of it being anti-OSS, doesnt mean that they are right in any aspect. Your comment about disabling email in outlook shows your total lack of knowledge about how a business is run. No business in their right mind would spend money on something, then disable its primary function to use a third party product which is best suited for a niche of users at best. I use thunderbird, however, I dont try to pretend its something its not (as is the case with most of the firefox/tbird fanatics). You claim that its microsoft's problem that t-bird doesnt interface with exchange. Can you explain then, why several other email clients CAN interface with it? Can you explain why the API's exist to allow other clients to interface with it and have been in use for several years?

Re:Stupid

[a.d.trick]

Maybe in the utopian land of happiness and glee. But for those of who live in the real world, it doesn't work so well. The fact is that software is buggy, and the more features it has, but buggier it tends to get. Security isn't a black and white thing. Most of the real decisions us real people have to make is based on a number of factors that we aren't quite certain about. Something like HTML email provides a much larger surface of attack and potential places for programmers to screw up. The most mail client exploits are related to HTML email (including less trivial things like phishing).

I use Firefox for web browsing. All things considered, Firefox is fairly secure, but I would be rather foolish to think that the whole thing is bug free. On the other hand, it allows me to use some extentions that really improve my security in other ways (encryption of stuff). So for me, it works out fairly well, but there's always a chance that someone might exploit it (In reallity, social enginneering is probably much easier though).

[mackyrae]

There are ways in HTML email of inserting 1-pixel transparent gifs which have unique load addresses based on who opens the email so that the sender know which people they mail read it. That's how spammers know if you open the spam they send. It's a sort of tracking cookie image.

Yes, from the vi/emacs flamewars it seems geeks are above that sort of thing, right?

People don't work with applications, they work with data. Say you start out writing a bullet point list. Then you see that you need some additional columns with a few formulas. Then you want to run some statistical analysis on them. From that you want to create a graph, modify it a little then add some logos and backgrounds before you want to send all this in an editable format to a friend of yours.

Maybe that involves:
* Word processor
* Spreadsheet
* Analysis tool (ok, overkill)
* Vector graphics tool
* Raster graphics tool
* E-mail tool

...but I could easily see how you'd like a tool that'd morph into any of those as you like, which could let you do all sorts of things like changing the base data = recalculate, update graph, apply all transformations and ask if you want to send an updated version to your friend comp+ete with revision control. In an ideal world, huge monolithic apps that contain everything including the kitchen sink sound good. In practise all it normally does is cover its weak spots by being part of a suite, with little fancy cross-integration.

Still ways to get email from outside the network

[Sepodati]

Although vanilla access to OWA is being blocked, there are still ways to get to your email from outside of the network (mainly what OWA was used for, anyhow). You can VPN into the network, log on to OWA using your CAC (common access card, smart card, etc), use your Blackberry (assuming your rank is high enough to get one ;)).

So instead of just plain old OWA sitting out there waiting for anyone to type in a username and password, they've upped the security a little bit. Yes, it's making us jump through hoops a little (for myself, need to stand up an ASA5510 as a VPN concentrator to receive outside connections), but it's not impossible.

Besides... not being able to check your work email from home can only be a good thing, no?? I know, I know, it's for people on travel, leave, etc. too...

As for the "blocking" of HTML email, can't say that I've seen that at all. Maybe it's only for emails that originate from outside of the network since we use HTML email all the time from within Outlook (formatting is useful in this case).

Moronic Policy

[mwilliamson]

As long as stupid users dictate policy (and it always seems to be the most idiotic, uninformed, timetable pounding and ego-blinded of all users usually are in the upper echelons of an organization), security problems do to software choice will prevail. This is how microsnot products usually get pushed into an organization. Score one for the DoD getting rid of freaking html-mail and outhouse web access. One can only hope they s**tcan ms-exchange while they're at it.

Re:Moronic Policy

s/do/due

Re:Moronic Policy

[Sod A Dog]

This move is good, but it's still just a drop in the bucket, and they'll never drop ms-exchange while they're on their current contracts. The DoD likes to sign contracts that it can't get out of, even when the service provider is doing a terrible job managing and/or maintaining the network.

NMCI, the Navy - Marine Corps network, is one of the worst intranets I've ever seen. Poor support, poor reliability, slow clients, crash-prone servers, poorly implemented and mandatory smart-card login, not nearly enough bandwidth to go around, etc., etc., etc. When the senior enlisted man in the Corps can't log in for a week because his account got borked, there's a problem. There are platoons that have hired independent contractors to come in and build small networks that actually work, and they only use the government computers when it's absolutely necessary. Every single user of NMCI hates it and wants it dropped like a bad habit.

But they won't replace it because they locked themselves into a ten year-long contract and the brass says that it would cost billions to fix the damned thing. That's a poor excuse - the DoD wastes billions of dollars every month. Seriously, if you work for the DoD, don't expect anything related to your computer to work properly.

"This is a bad idea? It's not going to work? It's going to cost way too much? It's going to piss off everybody who has no choise but to use it? Perfect."

Good! HTML email is very annoying. Most of the time it doesn't display as intended anyway. Many clients will only support a safer reduced set of html thus only parts of the page will display properly. This makes the page even harder to decipher. HTML email is really only useful for spammers and advertisers usually anyway. If something needs to be that heavily formatted, attach it as a word processor document. If you can't get a basic idea across in plain-text, then the problem probably isn't because you are missing your bold tag.

Off the top of my head, here's a use to which I've put HTML email in the past week and I found it useful. It was something like:

[jigjigga]

good, no reason to have flashy html junk- especially in an environment that needs security!

Temporary?

[Bluesman]

This appears to be a temporary measure based on the current threat level.

If the Infocon levels work anything like the other readiness levels in the DoD, then a shift to Infocon 4 requires a change (temporary) in policy. So it seems that a shift back to level 5 would mean HTML e-mail is no longer blocked.

It's like after 9-11, when all DoD installations had much stricter physical access rules and extra guards at the gates.

Which is a shame, because saying goodbye to html email entirely would be fine by me.

Re:Temporary?

[Locutus]

good point but another option is to put an email cleanser inline to remove all problematic formating. Also, because they will probably not give up Microsoft software for this, they have to realize that a major change is needed for longterm protection.

Blocking? Looked to me they were just converting.

[MysticOne]

I work as a contractor to the Navy, and we received e-mails a few weeks back saying that HTML e-mail would no longer be allowed. However, they weren't blocking it, merely converting anything that was HTML to plain-text or RTF. I've not tested by sending an HTML e-mail to my .mil address (gonna try that in a few minutes), but I don't think they're actually blocking it.

Re:I like some HTML email

[LiquidCoooled]

I agree with this.
A basic text formatting subset of HTML to help get the message across without any of the risks of full DOM support.
Slashcode handles bold and italic and lists (I think) and a few others but anything else is culled.

I feel dirty whenever I have to switch from flat-text mails.
The way Outlook shares its email HTML properties with explorer gives me the shivers.

Re:I like some HTML email

[EvanED]

Nothing is terribly wrong with asterisks, but

-formatted lists look nicer. (Especially if you have multiple lines with a proportional font, because then it gets indented correctly.) Just like nothing's wrong with writing bold text with *blah* and similar things, but the html version is still better looking.

Re:Blocking? Looked to me they were just convertin

[Anonymous Coward]

Yes that is all they are doing. In fact, if the formatting comes across screwed up, there is an option to restore html view. Not sure just what rules are applied and how the emails are being affected. I do know I sent a table copied another M$ product and sent it to my supervisor, which he replied back to me. The table was completed screwed up in plaintext mode. However, I did have the option of viewing the 'original format' or something close to it that put the table back the way it was.

I've been doing this for work for ages

[Kris_J]

I determined a couple of years ago that in order for the small IT department of one (me), to be able to keep up with potential Outlook security problems, I had to filter HTML down to Plain Text. When you've got a program that can be used to infect a computer just be previewing a message, you have to do _something_. Now that we've install Exchange (bleh), internal messages are no longer filtered, but thankfully the old filters for stuff going in (and out) of the company remain in use.

There's no excuse for it

Re:I know this is redundant, but...

[1u3hr]

why not offer support for [b]internal[/b] mail to be sent in Microsoft Word format?

For one thing, there are plenty of exploits for MS Word. So for going to a hugely bloated obfuscated binary format you'd gain no security. Like most peopel I get lots of messages sent as DOC attachments already. I usually view them, copy the text, paste into the original message as text (my client, Eudora, lets me do that) and delete the attachment, usually converting a 100k file into 1k text.

And Word files don't have a standard way to handle quoting and replying. So you get everyone making up their own "system", like "Original lines in blue, Jack's response in green, boss's remarks in Arial italic..."

[misanthrope101]

No one "writes HTML messages" in that they don't hand-code the HTML. But they routinely hit bold or italic, paste in tables, change font size and color, and so on. If HTML is so bad, how did this whole WWW thing take off? It isn't as if Amazon.com points to a plain-text list of books available, and an email address where you can send orders. HTML is useful. Allowing a subset of HTML function to allow for text formatting (tables particularly for me) would be useful. As much as I valued VT terminals (when we had them at work, "the system" went down less often) I do sort of like these newfangled conveniences.

Re:Doesn't that break digital signing?

"Problem is that encrypting has the bad side-effect of rendering the email unreadable via OWA"

Only OWA on Exchange 5.5, Exchange 2000, or the (future) Exchange 2007. Exchange 2003 uses a pre-installed ActiveX control to handle S/MIME at the client.

Re:Doesn't that break digital signing?

[Genocaust]

Or is the DoD just skipping the concept of digitally signing email? Actually the majority of the DoD signs and encrypts emails with the cerfiticates on our smart cards. And yes, there was push from the top to disable HTML email and have Outlook default to RTF, but it's still quite possible to change it to HTML. In my own experience, I still recieve HTML emails fine, too. Nothing on them is altered.

Re:Doesn't that break digital signing?

[marsonist]

The military issued Common Access Cards to all service members and DoD employees, that not only act as ID cards, but are smart cards which carry signing/encryption certificates. Slowly but surely the DoD is requiring these cards to simply log on to computers. Certain places have implimented a manditory signing policy requiring your private pin to send any mails. So to answer your question, many personel may not understand what exactly what signed e-mails are, but the powers at be aren't going to let that stop them from 100% implimentation.

Frankly, who cares? This is the DoD we're talking about; you want to use email to communicate with them, you play by their rules.

data + code = screwed

[Duncan3]

Yay! How profound that what we've always known finally made it into the heads of the military. If you mix code into your data, you're screwed eventually. No way around it.

That said, it's the JavaScript, not the HTML - formatting is data not code.

Now if only they would figure out the same about Word/Excel.

The HTML determines the rendering.

[khasim]

If the HTML is stripped from the body of the message, that means that the content of the message has changed from the context of the digital signature.

Therefore, the digital signature will no longer reflect the "data" portion of the message and will be invalid.

Re:The HTML determines the rendering.

[Beryllium Sphere(tm)]

Yep. S/MIME signs the whole package including the MIME headers. " Demime is designed to break signatures". Not sure, but it looks like PGP/MIME has the same problem.

You could still sign plain text and send that. Or send an attachment with a detached or builtin signature. Microsoft Word documents could have a signature and timestamp through the USPS Electronic Postmark system.

Re:The HTML determines the rendering.

[WED Fan]

O.K., one more time, and this is a message from the inside: Just the rendering is changed. When I get an HTML email on my .mil account, I see raw mark-up. It just does not render as html. It's the same as if you open a web page and view the source. It's signed, and unchanged. It is un-rendered.

If I get more specific, the DHS will visit you and use their little flashy things and make you forget. And, yes, we have those little...shit, what was I saying?

Re:The HTML determines the rendering.

[Cerebus]

An Outlook group policy is also supposed to be pushed to disable sending of HTML formatted messages. If your admins have been paying attention to the NOTAMs, that is.

I still receive all the HTML email I did previously - it's just converted to text formatting. A great deal of it is virtually illegible as some of the places I would receive email from had elaborate background files to their emails - now I just get a jumble of URLs at the start of those emails and have to search for the actual content.

The other problem is that (at least at my agency) we are still forced to create emails in Outlook RTF even though official policy was to switch Outlook to creating text-formatted emails (the option is locked thanks to our user settings). So our emails never get to where they are going looking the way they did when we sent them as they lose all formatting.

Re:why doesn't Microsoft indemnify such flaws

Do you seriously believe *nix systems have no security problems? Anyone who belies they're invincible is probably the easiest target around. Look at some reality. According to secunia.org:

- Windows XP Professional: 149 advisories in the last 48 months (3.1/month)
- Solaris 10: 84 advisories in the last 27 months (3.1/month)
- RedHat Enterprise Linux WS 4: 244 advisories in the last 23 months (10.6/month)
- OpenVMS 8: 1 advisory in the last 14 months (less than 0.1/month)
- OpenVMS 7: 9 advisories in the last 41 months (0.2/month)

*nix systems look like the loser here, don't they?

Also note that the Core Impact penetration testing tool has more Linux exploits than Windows exploits.

And then there were the Honeynet Project's results. They found that the average time to get compromised for Linux was about 90 days. None of the Linux boxes lasted even a year without getting compromised. Hardly anything to brag about.

Re:Slashdot strikes again......sigh.

[houghi]

And those admins also should disable HTML posting by defailt. Unfortunatly where I work, I can not even disable the HTML posting. :-(

The reason it will become another "bash Microsoft thread" is because they have caused it. They are also the reason that when you get a CC later in a converastion, you need to re-read the thread 6 times due to all the top, botoom and inline quoting with everybody using something different.

Even if everybody uses Outlook and topposts, it is almost unreadble after a while and that is only due to the fact that some programmer did not know ho to place the cursor at the end, remove the signature and put a '>' in all that one replies to.

NMCI goes even further

[truckaxle]

Any here that are forced to use the NMCI (Navy/Marine Corps Intranet) network know that reading any email at all can be a challenge.

A NMCI laptop takes over 10 minutes to boot and load the dozens of background processes and roving preferences. Once booted the machine is near useless performance wise.

Most, including middle management, refer to NMCI as No More Computing In-house.

In order to get idea just how bad things are, upper management conducted "customer satisfaction surveys". Even though the NMCI program office controlled the content, distribution, and analysis of the survey the results indicated overwhelming dissatisfaction. The NMCI program office has declined to release the raw data from the survey, instead issuing a release about the results. Rear Admiral J. B. Godwin III said releasing the results would challenge the "integrity of our data." Hmmm....

Most Navy labs that are under the burden of the NMCI contract maintain two networks, the legacy and the NMCI - the one to get work done on an the other to read email. This leads to double the costs and double the vulnerability exposure, and halves the resources to concentrate on security and usability.

Worst I hear that the Navy just extended the contract to 2010. Your tax dollars at work.

Re:NMCI goes even further

[Bios_Hakr]

NMCI is an admin's dream. CAC authentication means no more password issues. Locked-down desktops means no more shareware crap. Remote desktop and remote program installs means reduced admin visits.

Of course, paying $5000 for a shitty computer sucks ass. Plus what, $500 per user? On top of that, you have to pay retail for every app you want.

I have a CD-Burner in my NMCI machine. If I want NERO installed, I have to pay $300 for a cd-burner (because my build does not show a burner even though any idiot can look at the face-plate and see it's a CD/RW) and $100 for Nero.

NMCI is making out like bandits on this thing.

If you want to see the next step, look at the USAF's SDC program. They are using WinXP with some sort of Trusted Computing module. Unless an executable is digitally signed by the USAF, it will not run. Plus, the firewalls are on by default and highly locked. In a lot of cases, people going to SDC could no longer do their jobs. Even programs that were developed by USAF programmers in-house would no longer function.

On SDC, you can't even change your desktop background, color scheme, file view settings (I like a detailed list vice stupid thumbnails), or sound scheme. Most USB thumb drives fail to work, but you can still burn a CD.

On a clean SDC install, my computer shows 350MB of memory in-use on a machine that only has 512MB installed.

Re:NMCI goes even further

[Foolhardy]

If you want to see the next step, look at the USAF's SDC program. They are using WinXP with some sort of Trusted Computing module. Unless an executable is digitally signed by the USAF, it will not run.

IDK how SDC is implemented, but XP has a built-in capability to only run signed programs via Software Restriction Policies. An admin can set the default rule for binaries to disabled, and only allow specific ones identified by path, hash or certificate to be loaded.

Most of the other restrictions you mentioned can also be accomplished with the built-in group policies.

Re:NMCI goes even further

Re:I like some HTML email

I don't see the point of taking security risks and wasting bandwidth on email that "looks nicer." You want a nice looking email, format it as a webpage, and send your friend a link to the web page. Or print it out and stick it in the post box. My email program is instructed to display all email as text only and if it is full of crappy html that isn't filtered out, I hope it wasn't an important email because I deleted it. But I shouldn't have to bother; this junk should be filtered out at the server level and I'm glad the DoD at least recognizes that email security is more important than how nice it looks. I only wish my university would do the same :) Don't get me wrong, I love html, but it's not made for pretty-ing up email. It's made for hyper-text, which email should not be. Most email programs allow you to follow links that are part of an email message pretty easily, so what's wrong with sending the link to your browser?

[YomikoReadman]

I hate to say it, but this isn't anything new. The USAF has been moving in this direction for quite a while, with a service wide mandate that came down back in June. I don't recall the exact date, and since I'm not at work, I don't have access to the email which contained the policy. Additionally, There's also been a DoD wide move towards a 'Standard Desktop Configuration'.

All in all, DoD is moving towards more secure networks, and making things a lot harder for the user to screw up on their own, as well as making it harder for people on the outside to get in and do much the same. Will it be effective? I'm not sure, although I personally think that it's not going to happen as long as they're set on remaining largely windows based. Moving to Vista isn't going to happen anytime soon, so any improvements there aren't going to be available for the near future.

Good! As an IT guy it pisses me off!

[Aphrika]

It's not security, it's not size.. it's the bleedin' fact that every sodding day some bellend asks me how they insert >picture/video/stupidlink< into their email. I'm fed up with it! I'd rather feed their bones to pigs!

Merry Christmas by the way.

Re:I like some HTML email

[Watson Ladd]

Uhhh, the links are in html. So that's not going to work.

Re:I like some HTML email

[commodoresloat]

Uhhh, no they're not. At least, they don't have to be, and the email program shouldn't allow them to be.

Re:I like some HTML email

[commodoresloat]

The browser is designed for HTML and is configurable by the user (or the user's admin) -- you can say no java, etc. More importantly, the user has to take positive action -- click a link -- and to recognize that he/she is now going on the web to see something rather than looking at an email document stored locally as a file. You can also see where the nastiness is coming from if you land on a hostile script posted to a web page. Finally, you have a choice whether or not to click the link (and I usually don't). As long as the link is in plaintext (which is what I am advocating), you can see the address before you click on it, and you can decide whether it's worth the risk to see a photo of someone's dog you've never heard of. Embedded IMG tags and javascripts can be pretty nasty. Sure, these can be nasty in web browsers too, but at least you can make a reasoned decision before you wind up downloading some random script.

one more point

[commodoresloat]

And that is that the web browser is designed specifically to deal with html. New html security holes are dealt with by web browser patches on a regular basis (for the good browsers anyway). Email clients read html as an extra; their main function is to send and receive email -- hopefully they will be updated regularly too when new security threats arise, but it's more likely to be an afterthought. That's another reason why I'm a proponent of having clients do what they are supposed to do and then pass the other protocols on to other clients rather than trying to do everything within a client that was primarily designed for one protocol. Why have a web browser read email and an email program handling HTML?

software stupidity

[oohshiny]

It shouldn't be rocket science to display a piece of formatted text while disallowing network connections or scripts.

The fact that none of the major E-mail clients can be trusted to do this is a testament to the sad state of software engineering.

Re:software stupidity

[1u3hr]

The fact that none of the major E-mail clients can be trusted to do this is a testament to the sad state of software engineering.

I think it's more that to get the same look as intended by the sender using an MS client, you have to use the IE renderer built in to Windows. Otherwise people complained it looked wrong. And this was no doubt a lot easier than writing your own renderer and keeping it up to date.

Personally I stick with an ancient version of Eudora, which does have its own renderer. Sometimes it does look like crap when I get HTML mail, but I can usually work it out, and in the worst case, save to HTML and use a browser. One useful feature is the ability to edit incoming mail. I can select it all, convert to plain text, maybe delete any boilerplate disclaimers. Cuts the storage down by 80%. I know that businesses couldn't do this, but this is my personal stuff and I'm not going to be presenting it in court.

In most contexts, this is overkilll, but DoD...

[WoTG]

A lot of folks are going to say that this is overkill. A safe email client, patches, scanners, etc. should be "good enough". Well, if I was American (as opposed to Canadian), I'd say that this move by the DoD is a good one. Who cares if the risk is "small"? There is a higher risk with HTML email than plain text, and only marginal benefit. We are talking about an organization that needs to operate at very high levels of security.

NMCI: One of the great defeats in Naval history

[HangingChad]

A NMCI laptop takes over 10 minutes to boot and load the dozens of background processes and roving preferences. Once booted the machine is near useless performance wise.

That is so true. The Navy needed technical standards, not NMCI. The organization is too big and diverse for a one-size-fits-all solution. Application development has all but stopped outside of San Diego and EDS is running...or should say ruining...most of that. Layers of process and bureaucracy between the users and a usable product. What used to take months and cost thousands, now takes years and costs millions.

One example project...a working system built by just three developers in less than a year, part of the way through deployment when EDS moved in to take it over. Now there are 30 people on the project and they're scoping requirements...of a completed product in the middle of roll out. It's taken them almost two weeks to set up a test server.

When you take the billions invested, then add the man-hours wasted with people waiting on the help desk line the cost would be staggering. And I've never called when they weren't experiencing higher than normal call volume. When you have to play that message all the time, that means the normal call volume exceeds your capacity.

I will say this, though, after the 20-30 minute normal wait to get to a help desk operator, I've been very satisfied with them. That's the one part of the program that does work but doesn't justify the cost. I consider NMCI one of the great defeats in Naval history and casualties are 250 million US taxpayers.

Good to hear...

[SanityInAnarchy]

...The trouble is, they should've done this ten years ago. At least the HTML mail... It's a bit scary that the DoD is taking so long to get reasonably secure. Department of Defense, people!

Re:Good to hear...

[YomikoReadman]

While what you're saying is certainly a valid argument, ten years ago it wasn't a DoD priority. 10 years ago, any base that had any reasonable amount of connectivity was home to a NOC. Now, things are vastly different. Even bases which don't house them, never have, still have high speed connectivity.

Yes, it's the Department of Defense. However, Cyberspace and that realm in general has never been seen as a serious threat. It's only in the last 2-3 years that any branch of service has seen it as a viable battlefield. Even now, I'm not sure that the Armed Services as a whole are taking it seriously. However, I will say that if nothing else, the USAF is steering in a direction to take it on as part of their mission; The recent reissue of the USAF mission statement shows this: 'To provide sovereign options to fly and fight in Air, Space and Cyberspace'. Is it overly dramatic? To an extent, I'd say so. I'd also say that it's a step that needs to be taken.

I didn't say much about myself in my prior post; I'll do so now. I'm junior enlisted getting towards the end of my first term. I plan on staying in for quite some time. I feel that as a mission statement to tell the majority of Airmen what 'we', the Air Force, does, it's a bit off. However, it does say what we intend to do moving forward as a service. The Air Force intends to be the 'go to' option for any military action that the US needs to take in any of those realms. To be at the forefront of warfare based in Air, as is our traditional role. To be at the forefront in space, as we as a race begin looking beyond the atmosphere once again. Finally, to dominate in Cyberspace; denying haven to modern terrorists who seek to further the growth of their ideals on the internet.

I'll close with this; ultimately, this is all strictly my personal opinion. I say this as an individual, and despite my association/employment by the USAF and DoD, I support these and all other efforts in that capacity as well.

Cheers.

Converting Gateway

[morcego]

Why don't they simply add some format conversion feature on the border e-mail gateway ? That way, HTML messages gets converted plain text before delivery.
Then again, maybe they use Exchange, and can't implement something of this sort. I know it is, if not trivial, relatively easy to implement on many F/OSS MTAs (namely exim).

Re:Still ways to get email from outside the networ

[aliscool]

Dude here is correct. I work at the Staff war college that the article mentions. We set up a seperate CAC enabled OWA footprint and when one got turned off we flipped the DNS switch to the other. Install some middleware and use your CAC card. Much more secure and really no big deal to do.
HTML email is no loss. Folks can still send word docs or use rich text. We improved out security posture significantly.
People can still VPN is as well, again using their CAC card.
I myself have cut back on checking email from home as I usually leave my CAC downstairs and am simply too lazy to go down there and get it to check email.

Not blocking, just converting

[alodien]

I am a DoD employee and saw them take this step a few weeks ago (without any notice, of course).

They don't block HTML mail specifically, but every email is "converted to plain text" by outlook. A very, very big hassle, especially when the boss likes to highlight and bold text in his emails. He can still do this because Outlook doesn't force you to compose in plain text. However, when it gets to the employees it can be confusing due to the conversion process (especially to the "old" folks who can't figure out how to convert it back to HTML).

They actually have disabled many of the options in Outlook so there is no way to allow Outlook to always show emails as HTML. A major pain, in my opinion. I always have a need to format tables of infomation and embed them in my emails. Oh well, time to change my ways - life goes on.

My middle ground - both

[NotQuiteReal]

As an old boss once used to say, when presented with options - "Do Both!"

I read all my e-mail as "plain text". After all, HTML is plain-text too.

95% of the time that is all you need. Yeah, I can see they marked it italics or bold, but they are the same words.

If, after looking at the "raw" text, and I really think the formatting will convey some additional info, I might look at it as "html". Looking at the raw text gives you a pretty good idea if there is anything sinister about it.

In my experience, most HTML mail that "needs" HTML is junk mail, office jokes and the like.

Real business correspondence works on typed pages and plain text. No HTML needed to get your message across. Oh, but please do use a spell checker.

not entirely

[misanthrope101]

My workplace recently did something similiar. I was never crazy about flashy colors and zillion font options. But I do miss the ability to send tables as part of the email. My job frequently involves info that is best represented in a table, and the ability to copy/paste a table into an email was very helpful. Even allowing for the limitations of plain text,

Outlook did me the favor the other day of removing the "extra" line breaks, screwing up the already limited formatting I was stuck with. People will get around this by attaching a Word or Excel document. So the bandwidth costs are only temporary, till they figure out how to get back the formatting capability they had. The search function will be severely limited, unless Outlook will search through attachments.

I think forcing plain text is a bit severe. I understand the vulnerabilities of HTML, but allowing a reduced subset of HTML function to provide for text formatting would be a better (as in more useful for the end user) option. If the IT folks are the only ones whose convenience is being considered, I guess plain text is fine, and for that matter we should still be using diskless VT terminals. I don't often use the "threw out the baby with the bathwater" cliche, but I think it fits here. Allowing tables and italics isn't going to kill us.

Re:not entirely

[AaronLawrence]

Perhaps more to the point, does Outlook HAVE any HTML sanitiser? Mozilla does of course - perhaps they should just have switched to thunderbird? :)

Re:not entirely

[jonbryce]

Outlook 2003 does. If I remember correctly, it removes external images (such as , vbscript, javascript, flash, java and activex.

However, there are still buffer overflow vulnerabilities from time to time, and plain text email is much safer in this respect.

tables are HARDER, no?

[misanthrope101]

I concede your point, mostly. But my bosses want tables. I need the ability to copy/paste tables and queries from Access into an email, and limiting my emails to plain-text means I have to copy/paste the text, then manually format the table into pretty columns. And the first time a boss forwards my email to someone else, the formatting is screwed up again. I don't need the full spectrum of HTML capability, but tables are useful. Give me the tabular environment from Latex, or something. People will just adapt by sending attachments, and the entire plain text of the email will be "see attached." Does Outlook's search/find function work on attachments?

duh

[tovella]

most of the computers i have at home are set up to NOT accept html email. they've been set up that way for years. the DOD should have done this years ago. the also should have dumped MS Outlook years ago. these are the people (the DOD) who are supposed to keep us safe?

There is no infected html ...

[twitter]

... there are only broken email clients. It's the crappy OS that is infected not the protocol.

I like the way Kmail does it. It displays the silly html as text, with a button that asks you if you want it rendered. A quick scan shows you who it's from and if the thing is legitimate. Clients that are all or nothing and riding on an OS that's full of holes are the cause of the problem.

[Maxo-Texas]

You know... something like 12 tags and that's it.

bold, italic, underline, list.

More like when html started.

Formatting can help you to understand content.

What's wrong with a simple whitelist?

[thunderbug]

Simply allowing text helps server loading, but if the cycles are available, allowing selected, whitelisted HTML tags helps readability. The tags that make the whitelist should be benign formatting tags not unlike those allowed by /. (see "Allowed HTML" on the /. comment entry page.) ...to which I'd add 'pre', 'font' (only Courier, Helveticia, and Times), and those necessary to support tables of data. It wouldn't hurt to have such a list standardized so it is clear what will and will not be accepted.

Use MS Word instead!

[hadaso]

HTML is not really needed if formatting is needed. People can just write the message in MS Word and attach the file if HTML is unavailable! Really good choice indeed!

I use FastMail.FM webmail to read my email. I always view HTML. The HTML produced is a subset of the full HTML and most tags are "defanged" (including images and forms but lots of other stuff too). That's the correct way to read email. Banning HTML completely instead of allowing a secure subset in a secure environment means people would opt for formats that are much worse than HTML.

Re:Use MS Word instead!

[partenon]

Email messages don't need to be formatted. If they need to be formatted, then it's more important than a simple message. And that's the exact reason PDF is out there :-)

Re:I like some HTML email

[LilGuy]

You hit the nail on the head with that argument. That was exactly what I was thinking. Seems to defeat the purpose of blocking html e-mail.

Most html exploits are going to just link you to some stupid site that will actually rip open the security hole and infect you with god-knows-what. The e-mails themselves most likely are not going to be the culprit, but the actual website they so cleverly link you to will.

Hell, half the time the links aren't even clever. Phishing attempts are the worst if you have half an idea of what is actually happening when you browse the web. It's not hard to recognize that going to 122.235.151.62 is not the same as going to ebay.com to fill in your username and password information. But apparently even the DoD has completely clueless users... just the same as any other institution/corporation I guess and blocking html will be the easiest and cheapest fix I would imagine.

Less is More?

[Wingsy]

And so it goes, the world of Windows slowly but steadily moves forward in removing yet another piece of internet functionality, all in the name of security. Shame, isn't it, that because of Microsoft's swiss cheese products we can't seem to enjoy all the good things about the web that were promised?

It's not really a concern for most DoD?

[IonOtter]

It's not really a concern as far as the DoD is concerned.

If something needs a digital signature, then the person sending it is going to know how to configure their Outlook client to send in plaintext anyway. Our Outlook clients don't come "preconfigured" for signing, so the user has to know:

1. What a certificate is.
2. Configure ActivCard Gold on their machine to register the cert.
3. Navigate Outlook and find the security prefs.
4. Which cert to actually use with Outlook (there are 3 on each CAC card.)
5. To use THEIR cert, there are often more than just yours on any given machine.

From a DoD point of view, email coming in from "The Wild" from family and friends doesn't need a signature anyway, so it's not going to matter if a signature gets borked when the HTML is stripped. And if it's coming from a vendor who actually needs to use a signature, they'll be able to meet all five criteria mentioned above, and won't even use HTML.

OR...the NOC will simply add their domain to the whitelist and let it through.

Also, if the email is coming from a .mil domain, then it will arrive with HTML intact. If the generals/admirals didn't have the ability to automatically indent and inject their [Username] when replying, they'd collapse in a fit of frothing and twitching.

The DoD really hasn't ramped up the whole digital signature thing quite yet. They talk a big deal, but when it comes down to the Nuts&Bolts implementation, the only ones using it are the geeks, not the grunts.

As usual.

Re:I like some HTML email

[Steve001]

I think the move to plain text e-mail is a good one for the DoD. Besides the reduction of risk of malicious code, there are at least two other advantages of people using plain text for their e-mails:

• People concentrate on what their message says, instead of deciding what the message should look like. Per Dave Barry (when he was discussing word processing - paraphrased): For every minute you spend actually writing, you will spend 10 minutes deciding how it should look.
• The receiver has the freedom how to decide how the message should look, since appearance is separated from content. I can view a received e-mail in a font that is easy for me to read.

I agree with others that if formatting is so important, the best thing to do is include a formatted attachment with an e-mail. One thing to consider is that HTML provides only limited control over appearance, and it can vary based on application. Something simple like not double spacing between paragraphs is difficult (without the use of style sheets).

As the above writer suggested, a limited subset of HTML for e-mail might be a good way to go. I think a better, and more secure way, might be to develop an XML format specifically for e-mail which only allows for formatting and no executable code.

One feature of the format should be that the only e-mails that will be accepted are those that contain only legitimate tags. If an e-mail contains a single invalid tag (regardless of the reason) it is rejected and a message is sent to the sender.

Email needs to convey information

[hadaso]

Email messages need to convey information.
If I need to tell a student that
    2
  x
e   is not integrable in elementary tame then you say I have to create a pdf document for this one sentence? Most people I know attach a word document to do it because they don't know any other way. Or I can write $e^{x^2}$ like mathematicians do and tell my students that hardly cope with their math that they need to learn TeX before they can learn math. Or I can write e^x^2 and make it ambiguous. Or I can do what I do and write e^x² and send it in a message with Content-type set to text/html and the student will be able to see it in any mime compliant email reader that is set to render a minimal harmless subset of html (sadly Slashdot doesn't think <sup> is a safe tag for me to use in formating a post making me use "code" formating to make sure this is rendered with fixed width font. In Email I don't even  get the option to set fixed width font unless I use HTML or attach a file created in a word processor).

In real life most of the email I write is in Hebrew and there is no real plain text format that guaranties the recipient sees the same sentence I wrote. HTML provides the tools needed to control the way text is displayed without needing to create printable documents for every short note. When I compose English email I use plain text unless I need to convey information that needs html like math formulas or links.

Re:Email needs to convey information

[partenon]

You have a good point. And I almost agree w/ you :-) But then I got a question that only you can answer me... How do you write 1^(1/2) (or 1 sqrt 2) in HTML, w/out using TeX or other "complicated notation"? And if your students wants to send you math formulas for some reason, they need to use the right formula for the right problem (or the right tool for the right job). If they don't want to learn TeX, just show'em Word w/ Equation object.

Don't get me wrong, I got your point and it seems valid, but the *uses* of HTML in email messages aren't that wide/useful.

1^{1/2} in HTML

[hadaso]

1^{1/2} in HTML:

one way is: 11/2 and this is the way I would usually do it (with an html composer that has superscript/subscript buttons like all three different alternative composers in FastMail.FM's webmail interface).

Another way: 2

And another: 1½ (this is doable in fckeditor or in xinha using the "Insert special characters" button, see http://www.fckeditor.net/demo and http://xinha.gogo.co.nz/xinha-nightly/examples/ful l_example.html which actually has a cool equation editor :)

(I got the html entities from http://www.bigbaer.com/sidebars/entities/)

My student normally don't do these things. But then I can do the guesswork on what they mean, but I don't expect them to do the ame to understand what I say. Anyway most of my students use forums were they have an eqation editor that creates mathml (if they run winxp and can have admin privileges).

Actually, it's not really blocked

[poohsan]

I still receive html e-mail from outside sources. The default view (and preview pane) have been changed to plain text - you right click on the banner telling you that and convert it back to html - poof, an html message again. I can't compose html though, only rich text, and if the recipient id a DoD person they'll have to go through the same rigmarole to see my original formatting.

[Walles]

you must be able to accept attachments such as .zip and html mail

From TFA: "the current threat level does not bar the use of attachments"

Re:They aren't blocking attachments

[zerkon]

It isn't that the DoD is blocking HTML email, it is that outlook is automatically displaying all incoming mail as plain text (see http://support.microsoft.com/kb/307594) a good step in the right direction? sure, but since everyone just clicks the gray "display as html" bar at the top anyway, somewhat pointless. as far as attachments, I have yet to see any file be blocked for any reason (although I havn't tried emailing any executables)

Math in email using ASCIIMathML
