Clamav replacement for FreeBSD+postfix?

[Francisco Reyes]

Anyone using something other than Clamav in an busy FreeBSD+postfix 
environment for antivirus?

Clamav freezes often. Reading archives, seems this is not so rare 
in FreeBSD.

We even tried better machines, and gave Clamav more memory. That helped, but 
still seeing issues.

This is for an ISP, so experiences on other ISPs or large setups (ie over 
100,000 emails per day) would be most welcome.
