CentOS - Jun 2009 - Postfix question: How to reject email with a certain subject header

Hello everyone,

Occasionally I get emails which have a subject header of "Rejected posting 
to Blah", from a listserv I am on. Without going into a 10 page diatribe 
of why, I'd like to reject these automatically, sending them to /dev/null. 
I used to run Sendmail and that was pretty easy to do. How can I do this 
under Postfix under CentOS 5.3?

Any help is appreciated. Thanks!

Gilbert

Do you want to reject them or eat them and send them to /dev/null ?

If you want to reject them something like this would work:

header_checks = regexp:/etc/postfix/regexp_table

and in /etc/postfix/regexp_table something like:
/^Subject: This is the subject I want to reject             REJECT 554
Custom rejection message

are you using procmail as the delivery agent?  if so, you'd add 
something like the following to your ~/.procmailrc  ...

    :0:
    * ^Subject:.*Rejected posting to Blah.*
        /dev/null
