Hi I wonder if there is any obvious explanation of this problem (currently with Postfix 3.5.1).
I have several virtual domains defined in /etc/postfix/virtual forwarding emails to e.g. gmail accounts etc. E.g. (youmail.dk is the actual external domain) mycustomer.dk virtual postmas...@mycustomer.dk myc...@youmail.dk u...@mycustomer.dk myc...@youmail.dk mycustomer.dk. 86400 IN MX 10 mail.mycustomer.dk. mail.mycustomer.dk. 300 IN A 87.63.164.246 It is usually working fine, but recently mail sometimes get delivered using the local daemon to the luser_relay user and not to the external user using the smtp daemon Incorrect: 2020-04-25T08:21:56.742991+02:00 vennely postfix/smtpd[58433]: maps_find: virtual_alias_maps: hash:/etc/postfix/virtual(0,lock|fold_fix|utf8_request): u...@mycustomer.dk = myc...@youmail.dk 2020-04-25T08:21:56.743066+02:00 vennely postfix/smtpd[58433]: mail_addr_find: u...@mycustomer.dk -> myc...@youmail.dk 2020-04-25T08:21:56.802082+02:00 vennely postfix/smtp[58431]: 0E68A201E8462: to=<u...@mycustomer.dk>, relay=127.0.0.1[127.0.0.1]:10024, delay=2, delays=0.43/0/0/1.6, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10026): 250 2.0.0 Ok: queued as B1ADB201A1C35) 2020-04-25T08:21:56.802875+02:00 vennely postfix/qmgr[16285]: 0E68A201E8462: removed 2020-04-25T08:21:57.845860+02:00 vennely postfix/local[58436]: B1ADB201A1C35: to=<lu...@jth.net>, orig_to=<u...@mycustomer.dk>, relay=local, delay=1.1, delays=0.06/0.04/0/1, dsn=2.0.0, status=sent (delivered to mailbox) 2020-04-25T08:21:57.846156+02:00 vennely postfix/qmgr[16285]: B1ADB201A1C35: removed Correct: 2020-04-25T12:32:52.369132+02:00 vennely postfix/smtpd[83816]: maps_find: virtual_alias_maps: hash:/etc/postfix/virtual(0,lock|fold_fix|utf8_request): u...@mycustomer.dk = myc...@youmail.dk 2020-04-25T12:32:52.369180+02:00 vennely postfix/smtpd[83816]: mail_addr_find: u...@mycustomer.dk -> myc...@youmail.dk 2020-04-25T12:32:52.494233+02:00 vennely postfix/smtp[83803]: EE87C201E8462: to=<u...@mycustomer.dk>, relay=127.0.0.1[127.0.0.1]:10024, delay=2.8, delays=0.81/0.02/0/1.9, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10026): 250 2.0.0 Ok: queued as 58719201A1C35) 2020-04-25T12:32:52.494538+02:00 vennely postfix/qmgr[16285]: EE87C201E8462: removed 2020-04-25T12:32:53.247953+02:00 vennely postfix/smtp[83707]: Trusted TLS connection established to fpo9.mail.dk[193.201.76.57]:25: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) 2020-04-25T12:32:54.837993+02:00 vennely postfix/smtp[83707]: 58719201A1C35: to=<myc...@youmail.dk>, orig_to=<u...@mycustomer.dk>, relay=fpo9.mail.dk[193.201.76.57]:25, delay=2.5, delays=0.13/0/0.78/1.6, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 498S6Z57Gyz18VQ6n) 2020-04-25T12:32:54.838387+02:00 vennely postfix/qmgr[16285]: 58719201A1C35: removed Header of email to luser: Return-Path: <i...@rocketapps.com> X-Original-To: u...@mycustomer.dk Delivered-To: myc...@youmail.dk Received: from localhost (localhost [127.0.0.1]) by mail.jth.net (Postfix) with ESMTP id B1ADB201A1C35 for <u...@mycustomer.dk>;
