Selective alias depending on FROM?
in [Postfix]

From: Jordi Espasa Clofent on 7 Apr 2010 03:47 Hi all, I've a PHP script which is executed by 'www-data' (the httpd user) local user in Debian GNU/Linux box. I use this smtpd box as massive mailing remainder to all of our costumers. Because of that I need to know the costumers haven't could be contacted, so I want to redirect these bounces to dedicated mailbox. That's easy: www: failed_delivery(a)domain.com in aliases and rebuild the aliases. But the problem is local user 'www-data' executes a lof of scripts using smtpd and I don't want to redirecto all the bounces to mailbox failed_delivery(a)domain.com. �Is there any way to establish some pattern disctintion? For example, let's to suppose that my massive mails are always generated with FROM: warnings(a)domain.com: �Can I set up "www: failed_delivery(a)domain.com" in alias when _ONLY_ the FROM is warnings(a)domain.com? Thanks in advance.

This use of return-path is required; mail systems MUST support it. The return-path line preserves the information in the <reverse- path> from the MAIL command. Here, final delivery means the message has left the SMTP environment. Normally, this would mean it had been delivered to the destination user or an associated mail drop, but in some cases it may be further processed and transmitted by another mail system." I don't see cleary that it means the ReturnPath header is intended for what I'm looking for. Maybe I'm wrong, of course.

Do not try to modify any setting in postfix. Set your mass ( massive ?? ) mail application Envelope sender-id to a different sender-id. All mail servers would send the bounce messages to the Envelope sender id Thanks Ram

Use a different envelope sender. Bounces are always returned to the envelope sender address. To distinguish which recipient caused the bounce, you can use VERP.
