Stopping hotmail relayers

[Cornelius Koelbel]

Hi,

i think this is a very interesting idea. It is kind of "regular
expression" blacklisting.

- If the sender's domain is within a list AND
- His IP belongs to... AND
- if some more headers match some conditions


...I do not want to see the mail.

I am also courios if postfix was this flexible.

( I personally would not care if it was during the smtp connection or if
it could be handled by mailscanner after having accepted the mail )

Kind regards
Cornelius
