Bounces for viruses should not be sent.  They rarely achieve the goal of
fixing the problem as with too many viruses, they go to an innocent
bystander.  As with David, I've seen hundreds of thousands of emails of this
type sent to single users, etc. overloading their mailboxes, servers, etc.

If you insist on doing bounces, I would recommend a DB_File tie system to
send ONE or MAYBE two bounces and that's it.  Or something akin to vacation
where it sends the message once every 24 hours.  Anything more and you are
contributing to the problem and VERY POSSIBLY WHAT THE VIRUS WRITER wanted
to begin with.
