Hi all,

postfix-2.3.3-2.1.el5_2

If the subject does not match match /*.ABC.*/ and the recipient is
"fred(a)example.com" I want this email to be discarded.

This is not for spam detection it's simply an organisational
requirement.

Does anyone have a method to achieve this ?

Many thanks
Nick.

This requires a content_filter or milter that can compare both
the subject and the envelope recipient.

Probably SpamAssassin with some custom rules would be the
easiest (or maybe regexp-milter if it can compare multiple
items -- don't know, I don't use it).
