I want to process emails that I send out that bounce back. I can add a header to the email I send, and then getting email back I can simply run it through the script if the header matches and do some work to record the bounced email.
I did get the header_checks to run the script, (foo:bar=filter:dummy) but it did create an infinite loop like you mentioned. Another option I can get to work is to have the script process every email but check for the header. (I'd rather have postfix check that so I don't have to worry about it.) So I'd be interested in learning how you avoid the infinite loop. Perhaps there is a better solution I'm missing. -Dennis > >----- Original Message ----- >From: "Tyler Strickland" <[EMAIL PROTECTED]> >To: "Provo Linux Users Group Mailing List" <[email protected]> >Sent: Monday, August 15, 2005 3:01 PM >Subject: Re: Postfix Filters and header_checks > > >On 08/15/05 13:57, Dennis wrote: > > >>Anybody know how to get a filter to work with postfix? >> >>Here is what I want.. >> >>main.cf: >>header_checks=/etc/postfix/header_checks >> >>header_checks: >>/Match Something/ FILTER ??:?? >> >>All the documentation I find for the header_checks just says foo:bar >>where I put ??:??.
