Thank you! I'm thinking that I might try to read that infor and stick it
in a header and then feed it to Spam Assassin or try to track it and see
if I can find some useful patterns. My thinking is that there are major
spammers who may be rotating the IP addresses of the sending hosts - but
the name server records will give them away.
