Re: Clamav replacement for FreeBSD+postfix?

Anyone using something other than Clamav in an busy FreeBSD+postfix

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.

I can't address this specifically for FreeBSD as none of our FreeBSD
systems are running at high load levels, but I don't think that clamav is
the limiting facter. We're processing around a half-million messages a day
at an ISP through a single public MX server which runs postfix, amavisd,
and clamav to prescreen incoming messages, forwarding them to a cluster of
servers which do the mail delivery to NFS mounted Maildir stores after
doing spamassassin scoring. The load average on the border MX server
rarely gets as high as 1.00. Frankly I've been amazed that it handles this
volume that easily.

The border machine is running a Pentium(R) 4 CPU 3.20GHz with 2GB of RAM
which isn't a high performance machine by today's standards. The OS is
SuSE Linux Enterprise 9 SP2. We don't have any FreeBSD machines running
this configuration with significant loads for comparison.
