Its not a virus scanner. It catches a couple of easy virus header
signatures and it looks for particular MIME types. It does *not* scan
content, look in attachments or look at more than the first few
kilobytes of the message. If you have a system vulnerable to viruses
then you should think of additional protection.

It does kill off most of the mail worms seen to date quite nicely.

The probelmatic message was formatted as a bounce message - there is no
