Hi!
We faced the same issue.
We made our mailserver faster so that it is able to virus scan messages
within its databytes limit within the 60 seconds default SMTP timeout.
Another option is to have a "frontend" or submission server that
receives the messages and forwards them to the scanning server. This way
you have the SMTP timeout issue on a connection controlled by you. The
drawback is that the submission server will not reject virus messages on
SMTP level.
