Getting mail bounce loops ... not sure where to look to fix

RT Users

Hi folks:

We have RT 4.0.6 installed and working. Web site is running under
nginx and an fcgi process. Mail server on a different (remote) machine,
though we have postfix running/configured correctly on the web server
machine running rt4.

Sending mail from the rt4 machine works fine. No bounces, no issues.
Mail gets where it is supposed to go.

Sending mail from our mail server also works fine.

The web interface works fine.

Ticket updates and new tickets also “work fine”. But they spray
bounces on the rt4 machine to the postmaster account.

Looking at a pine output of the relevant mail account:

  • N 1 12:17 support@scalableinformatics.com (3K) RT
    Bounce: [Ticket #745] RE: Node MPI / infiniband issues?

  • 2 12:17      support@scalableinformatics.com           (6K) RT

Bounce: RT Bounce: [Ticket #745] RE: Node MPI / infiniband issues?

  • N 3 12:17 support@scalableinformatics.com (8K) RT
    Bounce: RT Bounce: RT Bounce: [Ticket #745] RE: Node MPI / infiniband
    issues?

  • N 4 12:17 support@scalableinformatics.com (10K) RT
    Bounce: RT Bounce: RT Bounce: RT Bounce: [Ticket #745] RE: Node MPI /
    infiniba

  • N 5 12:17 support@scalableinformatics.com (12K) RT
    Bounce: RT Bounce: RT Bounce: RT Bounce: RT Bounce: [Ticket #745] RE:
    Node MPI

    If I respond to tickets by email, the outbound email gets to where it
    is supposed to (but I get these bounces). If I respond by web, same thing.

    It appears to work, we just get lots of the progressive sets of
    sprayed bounces into the postmaster account.

    I am not sure where to look on this. Any thoughts?

and it continues for a total of 440 messages.
