125 E-mail accounts is a rather negligible number. Processor type doesn't matter, but give it a decent amount of RAM (512; 1GB if you want to do decently-fast spam and AV filtering). Depending on if you plan to go POP or IMAP, I'd recommend doing something like a RAID1 array of 2 or 3 SATA hard drives; scale the size depending on how much mail you want to let people keep on the server. External USB drives work great for backups (read up on spare devices w/ RAID, if you can get a large enough external). I also like to have my servers send tarballs to each other, and have a central backup server, but that might be overkill for your situation.

If you're looking at buying hardware, I'd recommend something like a Dell SC-series (1425 if you want rack-mounting, they're nice). I find they can do the hardware a lot more cost-effectively then anyone else (even building it) as long as you don't mind using strictly Intel processors.

In my experience, I'd stay away from qmail for e-mail purposes, but hey, it's all about freedom.

I recently took a job at an employeer that has NO domain structure, just

Email is hosted outside (about 125 accounts), as is the website.
The email is thrown in as part of the website package, but they are
going to change providers again, and are going to have to migrate these
accounts to the new provider.
I'm exploring what it would take to move email inside.
I'm curious what hardware you build on. Do you buy Dell, HP, build your
own, or do something else?
What level of hardware would you use for an email only server with this
number of accounts?
What if you added print and file services?
What do you use for backup?
I've not built a Linux server for a business, just at home for a couple
of "hobby" domains (Currently CentOS 4.3 with a QmailRocks install).
Gentoo has only been on my desktop....
I have built LOTS of MS servers (enough that I can recite the license
keys...), but don't feel much like giving them the $$$ for this. (or
anything else, really, in the future)
Thanks in advance for any input.
Dennis
