Bug Description

Binary package hint: postfix

A user complained that her e-mail was not delivered to a recipient.
When inspecting logs of SMTP gateway, it was confirmed that qmgr dropped the message without even trying to deliver the message.

In the following log snippet pay attention to the message CFF81171B16 that was "resent" by a content-filter to localhost.
Note that you truly can't find any kind of delivery information ("status=..."). It was simply just "removed" without any further notice.

(Seemingly irrelevant parts of log intentionally kept here for overall illustration; DNS and IP addresses relevant to my employer changed intentionally.)

Not reproducible, unpredictable, IMHO critical.

The machine is a month old installion of Ubuntu 6.06 w/all updates with no other apparent HW or SW problems, dealing with >30,000 e-mails/day.

Details upon request.

Any chance that syslog was restarted after postfix was started? That can cause chrooted services to quit logging, which could explain the log file appearance.

While it is possible (syslog-ng package was installed a week earlier), but let me note that:

1. the log was investigated after <s>user</s> two users had complained. Ignoring this would be inappropriate usage of Ockham's razor.
2. it is not obvious from the first log snippet, but you can actually find logs like

Oct 13 10:47:03 mailsystem postfix/smtp[29587]: 3418D171B96: to=<email address hidden>, orig_to=<email address hidden>, relay=pop3.YYY.ZZ[-----], delay=0,

If you still have the log from this, what does grepping for that queue ID (CFF81171B16) produce?
