I can only talk from experience; we are currently doing spam and anti-
virus checks in our inbound flow of around 600,000 messages per day.
To do this we have three inbound SMTP gateways running Sophos
Puremessage with Sendmail as the MTA.. These systems are quad proc
systems with 6 to 8 GB of ram. This is still not enough to handle the
inbound flow efficiently at our organization.
We have a system that handles similar quantities of incoming mail with a
single incoming MX server running postfix, amavisd, and clamav to do anti-
virus checking only, passing clean messages to a cluster of five machines
which do spamassassin checking and delivery into Maildir folders NFS
mounted on a central machine using LDAP authentication on the cluster
machines.
I wonder if you have tried postfix + clamav via clamav-milter in any
testing for potential system upgrades?
