They aren't bounces and I also told him the same thing off-list about BCC's.

 From looking at one email, appears to be a good string of new spam we
might need to look at. Looks to forge Hotmail but also appears to be a
waste because there is no call to action in the spam.

Agamemnus, if you want to send some of the emails to me off-list as a
zipped mbox or something, feel free and I'll see if I can find any
patterns. Your to/for idea doesn't have merit because as discussed
that's how BCC's work.
