Oh, I have a 2.8 GHz 512M RAM machine that runs all of this, just fine.  My 
setup is on a virtual machine that has 512 MB of RAM guarantied, but can have 
up to 1 GB at times.  If another virtual machine needs the resource, it might 
get the RAM and my VM has some dealocated.  That will cause things to go funky. 
 Amavisd isblocking some mail, but postfix blocks more using RBL's (35K/day).

There is also a couple of drupal sites and a wordpress site on the machine so 
its difficult to know which apache site might be causing the problem.  It 
doesn't appear to be dbmail.

Maybe your setup isn't exactly configured correctly? I'm running:

- Apache / mod_perl / php
- MySQL
- DBMail
- Maia ( spam filter )
- Spamassassin
- Subversion
- Cups

Then on top of this I've got compiz fusion and firefox running 24/7 ( home
server doubles as a downstairs internet kiosk ). This is all on a 1.2Ghz
Athlon with 512MB! It all works amazingly well. Admittedly it's not the
fastest thing in the world - it's usually got more stuff in swap than in
memory, but it's very reliable. And it's Gentoo ( same as original poster
was asking about ). It serves 5 IMAP clients pretty much all the time.

My old work had basically the same services ( minus the compiz fusion
desktop ), but with a 2Ghz AthlonXP and 1GB of RAM, and it served 45 IMAP
clients. It had MASSIVE databases. As well as 30GB of email, we had pretty
much all the rest of our business data in MySQL databases, and a PDF-based
document archiving system. It was actually pretty damned fast, and also
very reliable. It was also Gentoo.
