Like this:
deny malware = */defer_ok
warn malware = *
message = X-Warn: Virus scanning failed.
(and/or) control = freeze
The result of the malware condition is cached, so the antivirus program
won't be run twice. However, scanning can only be done in the ACLs, so
the easiest way to make sure that nothing escapes the virus scanner is
to defer and let the sending host requeue the mail (*if* there is a
sending host that's not a local user).
