The problem here is not that the bounce was generated it is that
Cantor.suse.de accepted the message in the first place. As was stated in
an earlier message "25866@xxxxxxx" is an invalid address and that is
were the virus _warnning_ was sent.
What should have happened is that Cantor.suse.com should have "550 User
unknown"'d the message when it was posted by the t-dialin.net host and
that should have been the end of it. The message should never have been
scanned in the first place.
Check the headers for your unsubscription address
