Is there a way to stop anti-spam but not affect anti-virus. We have a separate spam firewall that is doing a good job, I just want to be sure everything internal is scanned for viruses. Also, I'm curious if just doing AV and not A/S will help speed up mail transfers...because currently with everything running, the MTA's are dreadfully slow....I've averaged 160 - 170 msg's/minute with services on and ~700 msg's/minute with them off. I'm running OS X on dual G5's with 2 GB memory.
