Anyone with enough expertise to decipher the example noted in this document,
http://www.postfix.org/FILTER_README.html
search for 'Filtering mail from outside users only' towards the end of the page. I'm not sure what those 1.2.3.4 and 1.2.3.5 are supposed to denote and what are we supposed to set them to ? The "foo:bar" didn't make sense either.
I think we're looking on the wrong place with Postfix. The spam came from Mailman. If mailman accept it, the mail server will consider it's an inside mail.

I've just learned that what is noted on the URL above does apply to postfix-2.0 as well.
Anyone ?
