I was talking about laptops moving from connection to connection sending mail thus mail submission. Port 25 as mail submission is depreciated by newer RFC's I beleive (might be incorrect on that one) anyway inbound port 25 blocking is an issue with your ISP get them to fix it or move to another provider. It's general considered a good thing to have at least one backup mail server for reliability BTW. In your case it's sounds like you have issue with your contract with your ISP they generaly have clauses against doing what your talking about on home type DSL and it's a feature of there business service.
SSL is a personal preferance as it's blocked less often and stops some brain dead applications from sending clear text auth.
What does the laptop issue have to do with anything. Mail client to mail server should go over the mail submission port not port 25. Perferably you wold be using the SSLed ports for sending and reading mail. Properly configured submission ports only accept mail from authenticated clients so general spam is not an issue (Spyware taking over mail clients and sending spam is) Anyway confgure your mail server and laptop corrently once and your all set. If you realy expect to run a mail server on a laptop I would sugest reading up on UUCP, mail servers are expected to have constant connections.
I think the Russians figgured out KISS while NASA figured out pork. Sometime we might get ourselved out of LEO and maybe some of those working Nuke rockets till then the Russians seem to have the best working technology lets use it and get things done.
It's technicaly capable of happening it's allready happening under linux particularly for use with asterix, linux appears as a headset picks up the phone and dials etc. It's a nice hack for people that just want a cell phone but want / need a pots line.
OK having done this before there are a few tips. Sepperate everything inbound MTA's, outbound MTA's, Web, IMAP, Datastores and filtering to scale you need servers with very different requirements at every stage. Glue everything together with LDAP or SQL just remember it needs to be dynamic assume that you need to seamlessly move users from one data store to another on a regular basis and expand partitions on the fly (LVM is your friend here). The ability to alter the data flow on the fly is a must to perform maitnence etc. SAN's can be your friend here as it makes moving data around easy but it can also up the cost (10k gets you a nice server with 4-5TB's of disk 10k dosent buy squat for SAN gear) if I could do it all again I would look at iSCSI rather than IMAP/POP proxy's/NFS along with with a cluster FS.
As to software side go with what you know unless it's just incapable of doing the job. I like sendmail the next guy likes qmail (programers like it lots of easy SQL hooks) but overall having the techs be knowledgeable in it matters the most. For some cool hardware bits that can speed things up look at solid state (RAM not flash) disks for temp spools as just about everything besides MS respects the commited to disk requirement for SMTP and thats a big performance issue.
Cute app, it's not correct in it's assumption that it can detect all software keyloggers. It can't detect sw ones the dont write out to disk (sending it out over the network would seem usefull) it also cant detect sw ones the write out to a fixed size file or write out rather sporadicaly say at shutdown (a few megs of memory would be plenty to cover all data input for a long time and no reason it cant grow say in swap)
Ew ServerXchange, actualy Virtuozzo and PEM from SW play rather nicly with load ballancers. You have to make the users data get mirrors any way you can (iSCSI and software raid rock for this) Hsphere has a similar tack but only officualy plays nice with NetApp (works with the OSS version ok though)
As to load ballancing it's realy a toy when compared to the hardware boxes and as few year old arrowpoint (now cisco) boxes can be had for under 500 used that go faster than any linux box can think of with less latency.
OK having run thousands of servers for years, I can say pretty surely that the number one issue with servers that get enough cooling is hard drives, then power supplies and then memory in that order. At three to four hard drivers per system we would have 5-10 failures a day of hard drives a PSU about once a week and ram about the same. There are stability issues with high speed procs where your going to have more system and service restarts but it's pretty rare to have one die that hasent been exposed to static (aka most home jobs)
It's called PCI and AGP are 32bit and need direct access memory blocks. Just like ISA has a hole at 15-16 megs. x86 memory has lots of holes and wasted ram all over the place. I have yet to see a BIOS that allows you to put in a 3.5 - 4 gig memory hole. Pretty much the simple fact is your going to waste some ram on x86 not much you can do about that.
Anybody know of a way to recover that ram? I wouldent mind an extra 512 megs on boxes with 8 and 16 gigs in them (The joys of 8 DIMM slots in a workstation:)
I have to second this one, I work for a fairly large (top 30 ish) registrar that used ot go through tucows if your having an issue and JD is not responsive get tucows to step in. Elliot and crew generaly do a good job.

Funny I have a DTV DVR that does HD OTA channels just fine. DTV does not offer a SD DVR that will do OTA only the HDDVR.
Or they could just not mess with the data and use ISP status (they are one) to shield agaist the RIAA etc under the DCMA. Rate limiting things does not get rid of there ISP status but banning things does.
OK I actualy do this for a living every now and then and your pretty far off. There is a limit to the number of channels avalible past the fiber. 188 of them last I checked but not all cable co's have upgraded there physical plant to support them all. Each provider would need a minimum of 2 channels to hook there head ends into (for practial purposes they whould need space in the CO or very near it)
And as to DSL your incorrect again, everybody does not have to put in there own dslams to make it work. Many get an ATM feed from the incumbents DSLAM and that is the first shared bandwith and ATM can and does provide garentee's as to bandwith use per virtual circut. Often the incumbent changes as much for this service as they do for DSL as to avoid competition.
Your still free to choose. The EU is not a fully capitalist system they do not like monopolies and have decided to put some checks in there power. Thats what governments do. MS does not have to do business in those nations but if it does it has to play by there rules. Governments are not people they are not clients they can change the rules in the middle and get away with it. They shold be the ballance to corperate greed, after all MS does not have it's own army yet.
Actualy your incorrect it's not theft it's not a tangable item. Copyright it a short term right of exclusive use. Read short term. Its intended to allow people a chance to make a profit on there works before they go into the public domain. This is a ballancing act of how long it needs to be there to entice people to do creative things and get rewarded for them.
At the time this was thaught up there was a fairly high cost of copping things of this nature mostly books, printing presses and such. The digital age has changed this. If you look at the law it's not even a felony theft is. It's a felony to knowingly distribute for profit but still not theft by statute.
This is not semantics the crux of the issue is how long is long enough to make people and companys want to produce a creative work.
OK I am and EE and this is just the result of piss poor planing and execution. Redundany power is expensive. It has to go all the way to the computer (yup each one needs multiple supplies) and you need auto transfer switches everywhere. Problem with one RU servers is very very few of them have redundant PSU's.
Redundancy is easy you just need N+1 of everything and transfer switches at every stage. (And thoustands to pay to eletricians to put it all in) These guys werent highly avalble they just had a piss poor A+B bus setup and the B bus was lacking:)
Ah guess you have never worked in someplace where there are no acceptable scedualed maitnence windows with outage.
Preproduction is key here generaly working of of split mirrors and the like to insure things are exact replica's. It's just an issue of procedure if you dont have good procedure here you wotn have good tests. So I would differ on the nigh-on impractical part as matches hardware and a good mirror is the same thing:)
Course I may be biased I work with exact matching boxes we I can bring up a server on any of the hardware at any time in case of failure.
Funny I live in CT were Ihave a good local Gov and a poor state one (we dont have county level gov for the most part it's just a state level orgizational unit) The town deals with the three big things schools, roads and parks well. Might be bacuse we have a civil engieer for a first selectment rather than a politician that all the civil things are done well. As to preparedness we do extreamly well with good radio communications (Nextel tower with gen backup behind the PD to suplement normal radio) and have excess fire engines in an ancilary building for our volenteer FD and enough people in the auxilery to man them an then some.
Were not so great with zoning that is something that will get you fired people want to subdivide and have there property worth millions. We also dont have many forest fires or floods so it's not a big issue.
I think your issue with local gov could be solved by electing people trainded to do the work insead of talking about it.
OK I'm a network engineer been one for 15 years. IPv6 does not make customer address space portable, it does make it easier to "renumber" but in no way does it even help multi homing. So you IP's from your provider are no more portable actualy since the rules for getting IPv6 space are harder pretty much anybody withou an AS does not qualify and there are 16 bits of those half of them allready used. v6 only deals with multicast and IP space as it's big wins. Funny the telco's dont want Multicast to work and the IP space thing isn't hurting anybody yet you can get all the space you can justify and pay for.
BTW I can do what you described with NAT and with Public IP space (yes I have a public Class C in my home:) but most people dont qualify for a/19 and dont have 2.5k to buy the block.
Funny AOL did this a long time ago. If you dont have a valid PTR record in DNS they wont take mail from you they did that a long tim ago. RFC does not say you need it but it says you should. All people are free to choose what they are willing to accept. I hate AOL personaly and profetionaly (wait till you get somebody forwarding mail to an AOL account and marking it as SPAM AOL blacklists the last server in line)
Funny worked at a startup 4 years ago and EMC tried to get my fired for not buying there 3.6 Mill 1.5 TB POS. Then the sales guy went to the I'm going to loose my job if you dont buy it.

Never ever buy something from EMC they fired there engineers years ago it;s a sales and marketing company. That and the fact they trust embeded windows to run the clarion line:)
