I've been running a mail gateway with Postfix, Amavisd-new, ClamAV, and 
SpamAssassin for about 3 months now running 5.2.1-RELEASE.  The server 
is a dual-AthlonMP 2200+ with 3.5 GB RAM and 3 200 GB drives in a RAID5 
setup using a 3Ware Escalade 7506-4LP card.

Had some problems with a test install of Courier-IMAP on that server 
when running the ULE schedule and ADAPTIVE_MUTEXES enabled in the 
kernel.  Trying to manipulate a folder with more than 10,000 messages 
would panic the kernel (spinlock held for more than 5 seconds, or no 
kernel memory left) and force a manual run of fsck on the 300 GB /home 
partition.  Switching back to the 4BSD scheduler without 
ADAPTIVE_MUTEXES fixed that.

The server has been running without problems for over a month now.  The 
server blocks about 5,000 spam and 4 - 6,000 virus messages a day, and 
lets through about 10,000 or so clean messages.  Handles mail for about 
15 domains.

Load average rarely goes about 2, CPU sits around 10 - 15% most of the 
time.  Works quite nicely.
