Here you go.
OK, we are a qmail house also. We run clamav frontwards and backwards on
the MTA. We also filter with a Barracuda Networks Anti-Spam/Anti-Virus
Firewall as the primary MX for all domains. This is a highly effective
Spam/Virus stopping engine and has reduced the CPU cycles and writes to
HD's by 50% on our MTA's.  Barracuda is inexpensive also.

Cheers,
