Tagging of IP adresses / Application-Database

I'm sorry for my inactivity on this subject, but let me just try to
get this back to basics:  The only thing I wanted was an attribute
which said "SMTP connections from these IP numbers shouldn't happen"

As it is today, we pretty indiscriminantly reject email from the
dial-in ports of a large number of (mostly USAnian) ISPs to limit
the amount of SPAM.

All I wanted was to enable ISP's to cooperate on this tactic against
"hit and run" spammers.
