(in advance) 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.
