-> Communigate Pro: if I don't get to futz with the source for integration and value-add, I'm not interested.
CGP has a well-documented api for all kinds of third-party integration. I have sucessfully integrated ClamAV and SpamAssassin to communigate.....so I don't really understand the need for source here. In fact - CommuniGate's flexibility in this area (the ability to interface with other applications) makes it easier to work with than any other mailer I've worked on before. What kind of value-add/integration did you do that required you to read or modify source?
I love open source as much as the next guy - but after having to deal with managing open-source mail servers for years, I don't miss it and you can have my CGP server after you claw it from my cold, dead fingers.
I agree with you about NFS, though. Either NetApp if you can afford it or x64 sun boxes running solaris if you can't is a really good way to go.
I have been running CommuniGatePro mail servers for years. They have all the features you're looking for and more. The main thing I love about CommuniGate is the fact that I have one application that is the MTA, IMAP server, POP Server, and WebMail all in one. No dependencies. No futzing around with PHP or config files for half-a-dozen different applications. And it also supports clustering. A low-end cluster would consist of 2 machines with a NFS or CIFS/SMB backend for the storage. They also support so many operating systems it's not even funny. Solaris, Windows, Linux....even OS/2! You can grab a fully-functional trial off their site and have it up and running in minutes. Check it out, you won't be sorry. Their stuff scales from small systems to really huge ones with millions of accounts. For example - UC Berkeley's mail system is CGP. You can check 'em out at http://stalker.com/.
I have always viewed any burnable optical disc as a short-term disposable item - I never seriously considered them as a safe medium for long-term archival storage. Up to the recent past, I would have agreeed with the recommendation that magnetic tape is a better long-term medium....but then I ran into the problem of trying to make an ancient tape drive work. These days, I use good old-fashioned IDE (PATA) hard drives in external IDE-to-USB2/FireWire enclosures for archival storage. The problem of the bearings wearing out doesn't happen if the drive isn't on. As long as it's stored in appropriate environmental conditions - it'll last > 100 years. I have a couple of them that I rotate offsite every two weeks, so one copy is at home and another is at the office. Simple, cheap and very reliable.
I second that recommendation. I've been running CommuniGate Pro for many years now, and I love it. There's a cellphone provider in sweden that is hosting over a million accounts on a single 8-processor server - but for your requirements I'd probably recommend looking into CommuniGate's clustering solutions.
And here's the translated text courtesy of babelfish:
The Surf terminals seem slow to come to the Internet access independently of the PC into travel - and newcomer Transmeta can probably cut itself a tidy piece of the cake for Internet Appliances. Gateway/AOL and S3 already announced appropriate devices; At Computex the Motherboard specialist FIC presented for the first time its WebPAD with a Crusoe CPU by Transmeta, developed under the code name Aqua. The device is equipped with a color LCD operates with Embedded Linux and is going to get according to manufacturer five hours of use from a fully charged battery. For the connection to the Internet an integrated radio modem is provided. The Transmeta processor already sections of the chip record (Northbridge) contains, is necessary beside the CCU only a Southbridge. Suitable building blocks offer at present both VIA and ALI. Will in the long run select which manufacturer FIC for the internal Web PAD, is certain at present just as little as the selling price desired.

I mean, geez....he could have at least gotten the new bills that don't have the border around 'ol Andrew.....this guy needs to change his meds.
http://www.bootdisk.com - you can get a fully installable copy of DR-DOS 7.0 there.
