We only processed around 300,000 - 400,000 messages per month on our 
FreeBSD box, but we didn't have any issues with ClamAV with Postfix and 
Amavisd-new on FreeBSD 6.1 (dual-AthlonMP with 4 GB RAM and 400 GB disk 
in RAID5).  With one exception:  getting an MFS to work for Amavisd's tmp 
directory.  Worked for awhile, then it kept stalling mail delivery.  
Switching back to a disk-based tmp got things working, but slowed 
delivery down a bit.

We also used CommandAV as a secondary AV tool until our license ran out 
(thank god -- CommandAV is a horrid piece of junk on any OS).

After that, we used Kaspersky AV.  The FreeBSD package doesn't follow 
hier(7) even the slightest, but it is a fast AV scanner and can be used 
as either a mail gateway daemon (including its own SMTP server) or as a 
scanner in amavisd-new.

We've since moved our mail server over to a dual-Opteron setup with 4 GB 
RAM running Debian Etch (64-bit).  More for political reasons than 
anything.  Unfortunately, there's no 64-bit version of Kaspersky as of 
yet, so we're only using ClamAV on there (haven't felt like getting a 
32-bit environment working on Debian).
