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

You missed a "/" to close the regexp...
If you want to discard the message you can use DISCARD instead of REJECT. See the ACTIONS section of "man header_checks" or the manpage here: http://www.postfix.org/header_checks.5.html
It should be something like:
/^Subject: Rejected posting to / DISCARD Delete returns from listserv
The "Delete returns from listserv" message will appear on your logs, so it will be easier to see which (or how many!) messages are being discarded.

Eat them and send them to /dev/null.

Yes, but I'd rather eat them and send them to /dev/null. Any idea on how to do that?

The problem with that approach is that its global to the server. I dislike putting filtering rules like that in the system, and prefer to do them on a per user basis, hence my postmailrc suggestion (except I don't know if CentOS uses postmail as the delivery agent for postfix)

I don't believe it does. At least not with a standard postfix configuration.

Hey Filipe, John, Michael,
Thanks for your help on this. I do want a global rejection in this case, so this works out well. Thanks so much everyone!!!

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
