The Imminent Demise of SORBS
An anonymous reader lets us know about the dire straits the SORBS anti-spam blacklist finds itself in. According to a notice posted on the top page, long-time host the University of Queensland has "decided not to honor their agreement with... SORBS and terminate the hosting contract." The post, signed "Michelle Sullivan (Previously known as Matthew Sullivan)," says that the project needs either to "find alternative hosting for a 42RU rack in the Brisbane area of Queensland Australia" or to find a buyer. Offers are solicited for the assets of SORBS as an ongoing anti-spam service — it's now handling over 30 billion DNS queries per day. An update to the post says "A number of offers have already been made, we are evaluating each on their own merits." Failing a successful resolution, SORBS will cease operations on July 20, 2009 at 12 noon Brisbane time. Such a shutdown could slow or disrupt anti-spam efforts for large numbers of mail hosts worldwide.
A blacklist that charges you to get your IP removed will inevitably block far more than real spammers.
Oh my god the spam is burning, burning I tell you
"Such a shutdown could slow or disrupt anti-spam efforts for large numbers of mail hosts worldwide. "
You're kidding, right?
They have done more to give legitimate anti-spam efforts a black eye than ANY legislative attempts to 'solve' the problem ever could.
I -used- to believe that 'collateral damage' was a legitimate 'tactic' in the fight against spammers. I've grown up since then.

I don't know if this is subterfuge, but:

Any mail admin who's depending in any significant way on the anti-spam wasteland of SORBS should be on their way to apply for jobs at local fast food restaurants as soon as possible. Even if someone handling spam control for a decent size business actually believed in SORBS' accuracy or effectiveness, the only effect of SORBS disappearing from the face of the Earth should have is a slight uptick in spam being caught by filters slightly further down the path to their users' mailboxes.
Seriously, is there anyone out there who isn't use a multi-tiered, inter-connected array of spam filtering methods at this stage of the game? ~96% of the mail going to my users is spam. My worst offender has some ~5300 messages a day of spam being filtered prior to reaching their inbox. If my best filter were rendered worthless tomorrow, I wouldn't expect to hear any complaints from users. (of course, I'd be pretty unhappy.)
I think honeypots are probably my best weapon again spammers at the moment, followed by my keyword blacklists.

I run an ISP in the midwest. SORBS has caused so many problems, I don't want to bore you all with them here. I briefly talked with Mr(s?) Sullivan via email back in 07 about several problems he caused by blocking subnets we had on both Nuvox and XO. His response to my email (which was long but detailed), I paster here for brevity:

How is what Michelle did any of your business?

Your parent is right. There does exist a set of clueless people who straight filter based on RBL's like SORBS. Sure, filter your home mail server any way you want, but the *second* you have third-party people using your system (or the second you run the mail server for a business), you should be outright fired for filtering based solely on something like SORBS.
That is because I dont waste my time calling you. I call your boss and your sales department. If you really are running a business mail server and filtering based on SORBS, you are basically clueless and I'll gain nothing talking to you Your sales staff though, I'm sure they'd be happy to know you are blocking my customers inquiries into your companies products. And I'm probably also sure that if you are the type who filters like that, they probably have a bunch of other issues with the way you run their systems and this just might be the straw that broke the camels back.
Wow. That's a lot of hostility there.
First off, I never said I used SORBS. I did some research first about which ones would probably be best, respond to delisting requests in a timely fashion, and could provide me with a list that was had a lot of maintenance. Spamhaus and Spamcop are fairly decent and AFAIK, they DO respond to delisting requests and don't just put IP blocks up willy nilly.
I'm hardly an idiot. If I could find an open source software package capable of doing what I require, I would have gone that way a long time ago. As it stands, I have to use a proprietary software package that does not allow me to weight the incoming emails based of *any* RBL's. I can only refuse the connection based on the RBL's.
My original point stands. You want to be so incredibly hostile and label anyone that dares to use a RBL (or maybe just SORBS, could you clarify?) as an idiot, but fail to realize just how many mail server software packages out there don't do what you are asking for.
Try taking the hostility down a notch or two, and if you are so knowledgeable about mail server product that do offer weighting based on RBL's, why not just post it here for people to read? Maybe there are people new to running a mail server, don't understand the implications of a RBL (which hardly makes them an idiot), and would gladly implement a better solution.
Or... you could just attack people personally and denounce them for being idiots without actually writing anything productive while foaming at the mouth.
A lot of people have had their lives turn into a living hell because of some listing on SORBS. Thus if it wasn't me who chewed you out, somebody else probably would have :-)
Spamhaus's PBL?* I filter on that... the friggen ISP's make up most of that list. I'm pretty damn sure AOL and friends filter off that list too and my motto is "if AOL or Yahoo filters mail based on XYZ policy, I will too". Plus, you can get off that list on a web page.
It is SORBS that I have an issue with. SORBS was created out of pure spite. So my apologies random internet person :-)
* Excepting Godaddy who is fucking insane. Those assholes filter *URL's pointing to a PBL'd IP that are embedded in a message*!!! Worse, they dont tell you. Had fun learning that.

I asked myself the same question. In all fairness, that is how she signed off in the link included in TFS, but I still think its inclusion wasn't strictly needed for the "News for Nerds" aspect of the story....
Sorry if I offended you. That was a Suzanne Vega reference. Maybe SV isn't geeky enough for /.

The death of SORBS should be good news to any decent ISP mail admin out there. Nothing like being forced to pay to get your mail server IP removed from a blacklist because you somehow can't keep the thousands of residential customers on your service from occasionally getting a virus and sending a few spams.
SORBS sucks and has for years. Don't get me wrong, I hate spam as much as the next guy, but sometimes a few get through, that's just how it is.
Luckily we haven't had much trouble with them lately since it seems that the vast majority of mail admins came to their senses and stopped using SORBS... frankly I'm surprised they need that many servers.
Sigs are awesome huh?
I recommend Spamhaus XBL and Spamcop Blocking List .
Spamcop used to have problems, but I think they resolved them a couple years ago.
Back when http://stats.dnsbl.com/ was operational I used their data to give me a quick leg up on figuring out which lists to look at. Then I checked out the lists for how they operate and then did a performance analysis.
Aside from policy/operation, two things that were particularly important to me were false positives and overlap. These lists get very low false positives and they combine nicely.

I appreciate your apology, and your comment didn't (in and of itself) offend, just the moderation. I definitely didn't get the reference and it would appear, according to Suzanne Vega herself (scroll down to interview excerpt), the song was certainly written with good intent.
All that said, and having nothing to do with your comment, I'm not thrilled with Vega saying, "...I found out she wasn't really a girl," (emphasis added) in reference to the song's inspiration. Again, I don't think Vega is coming from a transphobic or hateful place, I just want to point out that that's not generally considered respectful language. (This isn't directly specifically at you, MichaelSmith, just more a general note...)

PS - I know I've been spoiled by the Internet, because I'm frustrated I wasn't able to imediately find an audio and/or video version of As Girls Go, so I could check it out, with a 30 second Google search...
And I realize you aren't the kind of idiot who blocks based on SORBS (or god forbid SPEWS, remember them?), and you are an ISP so if you were filtering based on SORBS you wouldn't have much business anyway, so I'm not really talking about you--I'm talking about small to medium sized businesses and other hotspots of cluelessness... "Me" in this case is my ISP and my customers trying to send email to *you* and your funky smelling email servers. In other words, imagine if some asshole listed *your* ISP or one of your upstreams in SORBS... Your (er, my) customers are now bitching to *you* (er, me). This is what I'm ranting about here.
If you are filtering inbound email based 100% on SORBS, you are clueless and it would be a waste of my time to deal with you. Why? Either you are ignorant (thus it wouldn't do me any good anyway) or you are an asshole who does this for kicks, in which case you'd tell me to FOAD. As such, talking to you is a waste of time.
You are the IT guy. Why would they listen to you? The probably already hate your guts for installing some other spite-ware or have them change their password every week. They dont listen to you and they dont like you (again, I'm not talking about you sir, but the SORBS filtering BOFH guy--ISP's are typically not the type to filter this way anyway). My calling them is just more ammo to go after you. It is politics my friend :-)
Funny enough, AOL has a 24 hour 1-800 number you can call to talk with the postmaster.
Can you provide all the domains you host, so that I can get as many mail admins together to arbitrarily block your servers, and demand "donations" to unblock them?
Thanks in advance, you worthless pile of trash.

This is the best news I've heard all week!
SORBS is a blight on the anti-spam effort front and should have been run out of town on a rail years ago. It has done more damage to the perception of anti-spam lists than any other single entity on the internet. Hell, some spammers are better behaved and have better morals than the operator(s) of SORBS. I would literally turn to Microsoft or McAffee for anti-spam solutions before I'd even consider SORBS.
I hope the dirtbags that ran SORBS end up destitute in a gutter somewhere.
Yes, it was. Without it, those of us who used to have to deal with "Matthew's" temper tantrums when our mail servers ended up on his blocklist would have been confused as to his wife or sister was now shutting things down. kdawson's comment explained the issue simply and directly, but without trampling on Sullivan's privacy too greatly.
God invented whiskey so the Irish would not rule the world.
kdawson should've included the disclosure that SourceForge, one of Slashdot's sister companies, is a sponsor of SORBS. There's an ad on the right side of the SORBS main page touting this fact, so it's not like it should've been difficult for him to find to point out in the summary.
God invented whiskey so the Irish would not rule the world.
Obviously you can't turn that off. I said "stop blocking based on SORBS". Huge, huge difference. And yes, there are idiots who block based on nothing more then SORBS. Ask me how I know.
I just want to point out that that's not generally considered respectful language
I'm not so sure that holding a different definition of the word "girl" than you do is really disrespectful. I get what you're saying but you've got to understand that to the population at large there is a difference between someone born biologically female and someone who surgically removed their genitals and started hormone therapy (or whatever other combination of measures you took to legally change your gender). For example, you never could and never will bear a child. Not that all women can, but they've generally got a higher likelihood of being able to do so. So people like to have different words for those different things. You've got to face the music, to Joe six-pack you're not a girl, you're a post-op transsexual.
I get what you're trying to say but I also feel like you're trying to strongarm others into changing the definitions of their words. If somebody doesn't think you're "really a girl" and you take offense to that, you're just picking a fight over semantics. Go ahead and wait until they say something really inflammatory and hateful before you bust out the righteous indignation, you'll win more hearts and minds.
The reason SORBS is so universally reviled by a lot of the anti-spam crowd is because the creator and the whole cadre of folks that maintained (and I use that word hesitantly) really didn't seem nearly as interested in battling spam as in enforcing their own bizarre view of who should and should not be sending email. The entire ethos was abusive and ego-stroking. The last time I had problems, the one thing I noticed that was different than my old battles with this pack of scumbags was just how few mail servers seem to be using it now. Hotmail was what forced me to even bother dealing with it, because my employer does a lot of correspondence with people on Hotmail addresses (another cancer on SMTP). My general attitude about mail admins who reject messages because SORBS blacklists my IP address is "fuck you", because those admins, as I've said elsewhere, are either morons or just lazy and don't want to put the effort into building a good, solid, rugged SMTP server.
What I can't believe is that SORBS still has some defenders, when my experience from the years when I was working most of my days as an admin for a few hundred domains was that SORBS was just as bad as spam. I really do hope that it is allowed to die, and maybe a few more retarded mail admins finally get the hint and start implementing measures that don't essentially poison SMTP.

Kind of off-topic, but Latvia has excellent net access speed. e.g., check out speedtest.net's stats. Latvia average download: 11.73 mbps. Australia average download: 4.92 mbps. In fact Latvia is their 6th highest worldwide. Speedtest.net isn't entirely scientific but is broadly representative in my experience.

I use SORBS professionally. It works. It stops spam. The few times IP space from our customers got listed, they got delisted within 24 hours after contacting SORBS by e-mail. All it cost me was registering an account for my employer at SORBS.
As usual in the discussion on blocklisting, Slashdot is being overrun by, ehm, 'legitimate biznizmen' and their supporters, and people who know jack shit about blocklisting and its history, but believe those who shout the loudest.

"I know I will be modded down for this": where's the option '-1, Asking for it'?
My first guess is that you're using Exchange. If so, ever since Exchange evolved into the emacs of mail servers (boy, it does a lot of awesome stuff, but it sure would be nice if they had a MTA in there somewhere), the "new hotness" has been to put a real mailserver in front of the Exchange server to "soften the blow" of incoming mail and deal with all of the crap. Of course, whether you go with an appliance like the barracuda, or some other server, it'll take a bit of money and elbow grease to get it to work well (eg validating incoming addresses against AD rather than just bouncing them off the exchange server, defeating the purpose).
While you are 100% correct in the sheer crap that is referred to as "SMTP" in Exchange, setting up a Barracuda to verify against AD (or LDAP) is drop dead simple. It's default LDAP search string covers both OpenLDAP and Active Directory servers out of the box. If entering in a couple of hostnames and making sure there's a path from your front-end server to your back-end LDAP infrastructure in your firewall is complex... then you probably are lucky to be using a Barracuda, since a hand built setup is beyond you for sure.
We have multiple domains, multiple LDAP environments, multiple mail servers (corporate: Exchange, our franchises are on a Zimbra cluster), yet we still have no problems even though Exchange has shit support for split domains. We even got single sign on to the mail quarantines to work relatively easily.
It's also the best bet for someone who needs local and remote clustering but maybe isn't an expert in Linux. Also, another advantage to such a person not having gone with a FOSS solution would be the vendor support. Even the front line guys at Barracuda aren't bad (well except that one moron who keeps posting strangely incoherant and ignorant ramblings about amavisd-new on the Postfix list the last couple of days - but I hear he doesn't work there presently). I haven't needed this, but a former client of mine has Barracudas in place, and their support routinely configures it for you.
Probably the biggest disadvantage to more experienced but time challenged administrators is that you can't put your own custom rules into Spam Assassin, although you can send their support any requests and they'll implement them.
I'll oblige ya. Here's the copypasta, filled in for your convenience:
Your post advocates a
(x) technical ( ) legislative ( ) market-based (x) vigilante
approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)
( ) Spammers can easily use it to harvest email addresses
(X) Mailing lists and other legitimate email uses would be affected
( ) No one will be able to find the guy or collect the money
(X) It is defenseless against brute force attacks
( ) It will stop spam for two weeks and then we'll be stuck with it
(X) Users of email will not put up with it
( ) Microsoft will not put up with it
( ) The police will not put up with it
( ) Requires too much cooperation from spammers
( ) Requires immediate total cooperation from everybody at once
(X) Many email users cannot afford to lose business or alienate potential employers
( ) Spammers don't care about invalid addresses in their lists
(X) Anyone could anonymously destroy anyone else's career or business
Specifically, your plan fails to account for
( ) Laws expressly prohibiting it
( ) Lack of centrally controlling authority for email
( ) Open relays in foreign countries
( ) Ease of searching tiny alphanumeric address space of all email addresses
(X) Asshats
(X) Jurisdictional problems
( ) Unpopularity of weird new taxes
( ) Public reluctance to accept weird new forms of money
(X) Huge existing software investment in SMTP
(X) Susceptibility of protocols other than SMTP to attack
( ) Willingness of users to install OS patches received by email
(X) Armies of worm riddled broadband-connected Windows boxes
(X) Eternal arms race involved in all filtering approaches
(X) Extreme profitability of spam
(X) Joe jobs and/or identity theft
( ) Technically illiterate politicians
(X) Extreme stupidity on the part of people who do business with spammers
( ) Dishonesty on the part of spammers themselves
(X) Bandwidth costs that are unaffected by client filtering
( ) Outlook
and the following philosophical objections may also apply:
(X) Ideas similar to yours are easy to come up with, yet none have ever
been shown practical
( ) Any scheme based on opt-out is unacceptable
( ) SMTP headers should not be the subject of legislation
(X) Blacklists suck
(X) Whitelists suck
( ) We should be able to talk about Viagra without being censored
( ) Countermeasures should not involve wire fraud or credit card fraud
( ) Countermeasures should not involve sabotage of public networks
( ) Countermeasures must work if phased in gradually
( ) Sending email should be free
(X) Why should we have to trust you and your servers?
( ) Incompatiblity with open source or open source licenses
( ) Feel-good measures do nothing to solve the problem
( ) Temporary/one-time email addresses are cumbersome
( ) I don't want the government reading my email
(X) Killing them that way is not slow and painful enough
Furthermore, this is what I think about you:
( ) Sorry dude, but I don't think it would work.
(X) This is a stupid idea, and you're a stupid person for suggesting it.
(X) Nice try, assh0le! I'm going to find out where you live and burn your
house down!
