It works for me. I forward a copy of every incoming email to my
BlackBerry and Gmail. Sometimes however, a spam/virus email with a zip
attachment makes it through the filters. Gmail however, blocks all email
containing zip files. Because I have used an owner alias for the
forward, the email is now bounced back to forward@internal.tld which is
an internal account which is periodically pop'd for bounces.
