I haven't been happy with CGP's anti-virus/anti-spam options
(specifically a lack of ability to do "during the SMTP transaction"
processing), so I tend to use a gateway approach.
1) On my production CGP machines, there is a group of sendmail boxes
that sit in front of them handling all non-SMTP-AUTH traffic. These
currently run mailscanner, but will shortly move to mimedefang (most
likely). I will be setting up a rule in the near future that tells the
CGP machines to send all messages which haven't been through the
sendmail machines to the sendmail machines.
2) On one of my development boxes, CGP doesn't answer on port 25. It
answers only to localhost on another port. Sendmail runs on port 25,
with mimedefang, and then delivers mail to the CGP port on localhost.
In both cases, SMTP-AUTH traffic currently goes directly to the CGP
process. One of the other "near future" goals is to get STMP-AUTH set
up on the sendmail side, and then all SMTP traffic will go directly to
the sendmail processes.
Using mimedefang lets me reject viruses and very-high-scoring-spam
during the SMTP transaction ... so that I don't have to either:
a) violate RFC's by quietly deleting messages, nor
b) hold on to and try to bounce messages that are probably heading back
to non-existent senders or forged senders.
Instead, my mail servers can just refuse to accept responsibility for
messages whose content is inappropriate.

Has anyone used or tried Panda for Linux? If so, what is your
feedback on the product? We use it only on the client machines but
haven't ran it on my email/web server. To tell the truth, I'm a
little scared to install it with running CommuniGate Pro, CGPSA,
Spamassassin without having a test server to see the effects in case
it screws something up.

John,
I use sophos too, but I though I'd drop the note on a
memory-and-performance-saver: Sophie is a deamon which received the
messages, processos them and returns the result "infected" or "not
infected" instead of forking a new sweep process for every incoming
email.
This resulted in WAY lower memory and CPU usage in my email servers.
