That's identd. If you use IRC ever, you should have that open and an
identd running. I have ippl running with identd, since occasionally
lamers try to knock down my box from public shell sites that have an
accurate identd running, so I can just turn around and email thier
abuse box so they can properly deal with the luser.

DUL, dialup list. A list of all known dialup IP pools, frequently
abused by spammers.

As far as I can tell, because Windows mail clients won't do
direct-to-destination mailing, but rather acts exclusively as a SMTP
