While it's possible, I don't think that's the problem, given that I 
see this type of attack about once per month from different places 
(usually China). Also, how would a single messed up DNS entry cause 
servers all over the globe to send these messages through my server, 
and in alphabetical order? It really looks suspicious to me. Am I 
just being stupid, or do others think this is a spam attack, too?

I got to thinking about this, and realized, it probably wouldn't be 
too hard to have a Code Red like virus that started up an SMTP server 
on people's machines without them realizing it. I wonder if someone 
has tried something like that? Of course, you could even just keep a 
list of open relays and send each message through a different one to 
be less obvious, too. Are these known techniques?

Thanks,
Darrin
