qmail is not relaying anymore
by lucmove from LinuxQuestions.org on (#5E6JN)
I had qmail running for many weeks, delivering mail normally.
Mind you, it's a special setup. It's only supposed to relay messages generated occasionally by a script run by cron. Nothing else. No other kind of mail.
It worked for weeks then it got silent. I found that there were 44 messages stuck in the queue. I managed to clean the queue then sent a test message. It's stuck.
I found this in /var/log/qmail/current:
Code:@40000000602a4b4737af0334 info msg 889958: bytes 280 from <c3po@homeserver.net> qp 4344 uid 0
@40000000602a4b4739b8a644 starting delivery 4: msg 889958 to remote master_luke@somemailservice.com
@40000000602a4b4739b8ae14 status: local 0/10 remote 1/20
@40000000602a4b473a2611fc delivery 4: deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/
@40000000602a4b473a2615e4 status: local 0/10 remote 0/20What else can I do to troubleshoot this?
