Greetings all,
I'm not sure how to fix this and am looking for suggestions and/or a=
clue...
One of my end users is getting the following error (real domain names=
removed)
Final-Recipient: rfc822; [EMAIL PROTECTED]
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; mail for domain_a.org loops back to myself
Here are the parameters used:
"[EMAIL PROTECTED]" is an IMail alias that goes to the mailbox=
"[EMAIL PROTECTED]"
Mailbox "[EMAIL PROTECTED]" has a forwarding order active to=
"[EMAIL PROTECTED]".
domain_a.org and domain_b.net are hosted on the same IMail box using=
different IPs.
The MX records for domain_a.org point to the Postfix/IMGate boxes:
10 mx2.domain_b.net
20 mx1.domain_b.net
The MX records for domain_b.net point to the Postfix/IMGate boxes:
10 mx1.domain_b.net
20 mx2.domain_b.net
(Note the reversal for load-balancing purposes but I don't think that is an=
issue here.)
The Postfix/IMGate box known as "mx2.domain_b.net" is set as the Remote=
Mail Gateway Host on the IMail box.
I would think the mail for "[EMAIL PROTECTED]" would be processed as=
follows:
1) Mail received at mx2.domain_b.net (or mx1.domain_b.net if mx2 is=
overloaded)
2) Mail passes various PF/IMG checks and is relayed to IMail Server=
listening on the domain_a.org IP
3) Mail processes via alias to mailbox to forwarding orders for=
"[EMAIL PROTECTED]"
4) IMail hands off the Mail internally to domain_b.net and deposits the=
Mail in the correct mailbox.
Obviously, this is being short-circuited somewhere. Here's what I think=
might be happening:
1) Mail received at mx2.domain_b.net (or mx1.domain_b.net if mx2 is=
overloaded)
2) Mail passes various PF/IMG checks and is relayed to IMail Server=
listening on the domain_a.org IP
3) Mail processes via alias to mailbox to forwarding orders for=
"[EMAIL PROTECTED]"
4) Mail is sent back to mx2.domain_b.net and triggers the error message=
referenced above.
Looking for comments, clues, pointers to RTFM, etc.
