I am running a list server that uses Postfix 2.0.18 (yes, it's a little bit creaky) as its MTA. On one of the lists, users are complaining that they are receiving repeats of one specific message from one specific person; the repeats are being sent out every 70 minutes. (Sounds like a requeue interval.)
When I check /var/log/maillog, I see entries like this (I've replaced the local-part of each address with "LOCALUSER"): Jun 18 00:24:16 ares postfix/qmgr[874]: 587564A7357: from=<[email protected]>, size=4031, nrcpt=1 (queue active) Jun 18 00:24:16 ares postfix/local[1935]: warning: 587564A7357: trace service failure Jun 18 00:24:16 ares postfix/local[1935]: 587564A7357: to=<[email protected]>, relay=local, delay=116238, delays=116238/0.03/0/0.05, dsn=4.3.0, status=deferred (587564A7357: trace service failed) That's all there is (every 70 minutes). The e-mail messages are identical, right down to the Message-ID header. The log entries all have the same transaction ID of 587564A7357. There is no "connect from" or "disconnect from" line associated with each new entry -- which makes it appear that the repeats are being generated by Postfix, not the MX at crs.loc.gov. While I was still thinking that these were coming from the external server, I put a rule into header_checks to block anything with crs.loc.gov on the From: line -- Draconian, but temporary. However, it didn't change anything -- lending credence to the indication that these repeats are being generated internally somehow, not arriving from the Blue Yonder. Any idea what's up? And sure, I'd be happy to upgrade Postfix ASAP if this is a known bug in 2.0.18. Else, while I realize that I really should upgrade to the current release, I'd prefer to wait until I have more time. (Postfix has been humming along flawlessly for so long, I'd damned near forgotten about it.) __________________________________________________________________________ Vincent Sabio [email protected] If you choose to reply off-list, please do not reply to [email protected]; your message will get lost in the spam pile.
