We've been having a similar problem wiht v3r1:  SMTP mail from our AS/400
to The Internet gets 'hung up' on the AS/400 and never makes it.  IBM
suggested changing the retries to make the messages fail, but we're back to
the same problem:  QxSMTPSRVR job starts and shows xxx outgoing messages
queued. Some get pushed out if SMTP is ended and re-started, but that's not
a guarantee.

IBM took some dumps/flight recordings and thinks our DNS server (at our
ISP) isn't responding.

I've tried changing job priority of the SMTP server jobs to run above
Interactive, but there are still messages queued.

No, they're NOT stuck in the DSTQ.  (WRKDSTQ)

Anyone have any clues?
