I have notice that most of the bugbear messages I have gotten, have been
copies of message posted on a mailing list I just sent a message to. It
seems smart enough to chose a message from the same list as the one I sent,
I know its not going through the list as the list strips all attachments.

> Our copies have subjects, message bodies, and attachment file names drawn

> Sophos makes brief indirect mention of this ("can look like

> Norman mentions it could reply to mail on an infected computer
> Another oddity on the copies we have received: the entire message body is
