Get an evaluation licence for BarricadeMX from Fort Systems 
(www.fsl.com). This is a *very* good anti-spam system that costs less 
than any of the other decent commercial alternatives. Even an old server 
should be able to handle near 1 million SMTP connections per day without 
any difficulty. Put MailScanner and SpamAssassin behind it to clean up 
what it misses and you have a *superb* system for very little money.

They do 30 day eval licences for free so you can try it out. It's very 
quick to deploy and test, and they will happily help you with that, as 
will I.

Give it a go, you won't be disappointed.
