[Avcheck] Scan only mails for some domains?

It is possible. We do it like this:
We have 2 IP addresses for our mailserver. We configured them like this in
master.cf:
# Incoming mail without virus scan
mail2.nederland.net:smtp
        inet    n       -       y       -       100     smtpd
                -o content_filter=

# Incoming mail with virus scan
mail2-scan.nederland.net:smtp
        inet    n       -       y       -       100     smtpd
                -o content_filter=avscanr

You can then let the MX point to the second IP address / hostname when you
want to have it scanned.

Michael said it couldn't be done, so it's possible that this is a bad
sollution. But it works great for us.

Good luck,
