Hi All, On one of our servers, we experienced this strange behavior.
A mail was sent to 2 other ids on the same virtual domain. LMTP delivered a warning and then after almost 24 hrs the mail was successfully delivered. Pls see the logs below : ================================================================================ # cat maillog | grep B082DCCEB6 Dec 9 13:24:25 ms1 postfix/smtpd[6462]: B082DCCEB6: client=unknown[192.168.x.x], sasl_method=LOGIN, sasl_username=x...@domain.tld Dec 9 13:24:25 ms1 postfix/cleanup[24260]: B082DCCEB6: message-id=<004801ccb647$d6a829e0$83f87da0$@domain.tld> Dec 9 13:24:25 ms1 postfix/qmgr[21077]: B082DCCEB6: from=<x...@domain.tld>, size=11809, nrcpt=2 (queue active) Dec 9 13:53:15 ms1 postfix/lmtp[20066]: warning: open active B082DCCEB6: No such file or directory # cat maillog | grep B082DA4218 Dec 10 11:59:27 ms1 postfix/qmgr[12420]: B082DA4218: from=<x...@domain.tld>, size=11809, nrcpt=2 (queue active) Dec 10 12:03:59 ms1 postfix/lmtp[30172]: B082DA4218: to=<y...@domain.tld>, relay=[relay-ip], conn_use=551, delay=81573, delays=81302/272/0/0.19, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=31000-14-551, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 9C664165F6F) Dec 10 12:03:59 ms1 postfix/lmtp[30172]: B082DA4218: to=<z...@domain.tld>, relay=[relay-ip]:10024, conn_use=551, delay=81573, delays=81302/272/0/0.19, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=31000-14-551, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 9C664165F6F) Dec 10 12:03:59 ms1 postfix/qmgr[12420]: B082DA4218: removed ========================================================================================= My questions are ==> a) Why did LMTP give a warning. Where did the message as mentioned in the Queue-Id go ? b) How was it picked up and delivered almost 24 hrs later with a different Queue-Id ? c) Why did it take so long to send this mail ? Assuming this happens again, can we reduce this delay time to something like, say 2 hrs ? Regards
