Granted the fact that it's a
well run MTA doesn't prove that forged messages or spam won't pass
through it, but in the world we live in a very small proportion of
unwanted mail is originated from well-run MTAs, so reputation at that
level certainly seems valuable.
I have in my notes an interesting tidbit from the MAAWG meeting in DC:
Carl Hutzler of AOL said that >70% of spam comes >>through the mail
servers of ISPs.

I will have to disagree with AOL.
I am not affiliated with this service at all, but if you go to
http://www.senderbase.org and just take a quick glance, you will see
that most spam comes directly from ISP client accounts whose providers
have not closed port 25.
