Viktor,
Agreed 100%. I'm updating the SQL now to return a command only when the
incoming address refers to a valid queue. The problem that originally
led me to post to the list was that the local delivery agent wasn't
setting 'Return-Path' and 'From' headers on one of my servers. As it
turned out, these headers aren't being set correctly on BOTH servers;
that was masked by the SQL error.
Now I'm trying to determine why 'Return-Path' and 'From' aren't being
populated. This is only happening for messages which arrive by way of
an external alias (hosted on an Exchange server over which I have no
control). If I send to an external address aliased to my local address
the message headers look something like this:
>From MAILER-DAEMON Thu Feb 5 15:40:37 2009
Return-Path: <>
X-Original-To: testinstance-supp...@thinkingphonenetworks.com
[ abbreviated ]
Received: from mail-ew0-f21.google.com (mail-ew0-f21.google.com
[209.85.219.21])
by exmf005-11.intermedia.net (Postfix) with ESMTP id 43E9F10ECA
for <test-supp...@thinkingphones.com>; Thu, 5 Feb 2009 12:40:32
-0800 (PST)
(Here, the alias is 'test-supp...@thinkingphones.com' and its target it
'testinstance-supp...@thinkingphonenetworks.com'. I used a personal
Google Mail account for testing.)
I don't know how to configure Postfix such that the local delivery agent
updates 'From' and 'Return-Path'. Based on the man page it looks as if
"local" does this by default. Perhaps the remote Exchange server is
producing headers which are somehow interfering with Postfix? I sniffed
the SMTP session to make sure Exchange wasn't actually sending a
Return-Path; it is not.
Regards,
Damon
