Hello, I'm dealing with a strange issue on a postfix server running multiple instances. I've set a maximal_backoff_time of 8 hours in the instance's main.cf. I can check it was actually applied with postconf:
$ sudo postmulti -i postfix-p26-o151 -x postconf | grep -E 'queue_lifetime|backoff_time' bounce_queue_lifetime = 5d maximal_backoff_time = 8h maximal_queue_lifetime = 3d minimal_backoff_time = 10m However, when I check the logs for this instance, I can find multiple occurences of deferred emails moved back to the active queue with the default maximal_backoff_time of 4000s. I've double checked the postfix docu mentation, the main.cf file should be private for each instance. Is this a bug, or did I forget a parameter? 2018-12-12T01:06:34.384322+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T01:07:40.017722+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[6667]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=386893, delays=386828/65/0.37/0.1, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T02:16:35.950068+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T02:17:37.859783+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[1443]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=391091, delays=391029/61/0.37/0.1, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T03:26:35.447677+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T03:27:34.835921+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[31192]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=395288, delays=395229/59/0.37/0.11, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T04:36:30.932122+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T04:37:41.922446+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[28194]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=399495, delays=399424/71/0.37/0.11, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T05:46:31.881443+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T05:47:46.309076+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[25988]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=403700, delays=403625/74/0.37/0.11, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T06:56:33.072730+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T06:57:54.902251+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[26065]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=407908, delays=407826/81/0.37/0.11, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T08:06:34.682500+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, nrcpt=1 (queue active) 2018-12-12T08:08:00.726228+00:00 pr-li-smtp00-0047 info postfix-p26-o151/smtp[28467]: C0E76483ECE: to=<aaaaaa...@aaaa.aaa>, relay=mx.AAAA.AAA[DDD.DD.DD.DD]:25, delay=412114, delays=412028/86/0.37/0.11, dsn=4.7.1, status=deferred (host mx.AAAA.AAA[DDD.DD.DD.DD] said: 450 4.7.1 Your email server DDD.DDD.DDD.DDD was temporarily blocked due to spam - contact us and report a problem (in reply to RCPT TO command)) 2018-12-12T09:16:37.731205+00:00 pr-li-smtp00-0047 info postfix-p26-o151/qmgr[31295]: C0E76483ECE: from=<ddaaddd.aaaaaaaaaddaaaaaaaaaaaaadadaaaaaaaaaaaaaaaaaaaaaa...@aaaa.aaaa.aaa>, size=28781, Regards, Brice Lopez
