Postfix que mng filling up maillog with multiple postfix/qmgr entries

[68chicayne]

I'm having some issues with my spambox running Postfix. The Postfix queue manager is flooded with multiply queues of the same message(s).
Below is a snip-it of the maillog.

Here's one example -

When I filter the maillog for message 19B3550676E (grep 19B3550676E /var/log/maillog), I get over 2500 entries for that message.

[XXXXX@mail2 log]# grep 19B3550676E /var/log/maillog
Nov 2 11:37:03 mail2 postfix/qmgr[4343]: 19B3550676E: from=<Christopherxxxx@com>, size=81406, nrcpt=1 (queue active)
Nov 2 11:37:06 mail2 postfix/qmgr[4347]: 19B3550676E: from=<Christopherxxxx@com>, size=81406, nrcpt=1 (queue active)
Nov 2 11:37:08 mail2 postfix/qmgr[4355]: 19B3550676E: from=<Christopherxxxx@com>...... and so on.........

grep 19B3550676E /var/log/maillog -c
2501

Any thoughts?

It looks like the messages are being re-introduced to the active queue every 3 seconds. The active queue is one of the four queues maintained by postfix and is where the majority of the work is done. Messages are first placed in the incoming queue and after passing trivial-rewrite are placed in the active queue. Normally from this (active) queue, the messages are sent for delivery, or if they can't be delivered, they get deferred.

There are timers that dictate how long the messages will stay in the queues and how often the queues are scanned to see if re-attempts need to be made.

In your case, something is putting the messages back in the active queue and you need to find out what. To do this, you may need to turn on debugging, which can be done in your main.cf file. The mail-log SHOULD contain messages showing the process occurring.

Here is an example from my log:
1)Nov 1 08:16:08 server postfix/smtpd[31325]: 08B951F4: client=server.debian.lan[192.168.0.49]
2)Nov 1 08:16:08 server postfix/cleanup[31329]: 08B951F4: message-id=<20091101131608.08B951F4@xxx.net>
3) Nov 1 08:16:08 server postfix/qmgr[2922]: 08B951F4: from=<ossecm@server>, size=2460, nrcpt=1 (queue active)
4) Nov 1 08:16:08 server postfix/smtp[31330]: 08B951F4: to=....
5) Nov 1 08:16:08 server deliver(...): msgid=<20091101131608.08B951F4@xxx>: saved mail to INBOX

As you can see, it was received (smtpd), cleanup, queued active, and delivered.

Please post output of "postconf -n"

Also, are you managing to deliver this mail eventually, or is it just looping through the queue indefinitely (or until it times out?)

Thanks for the replies.

Eventually mail does get delivered.
