Greetings, As promised: I'm back.
After processing about 740 mails, it is again. Via SSH based replication it isn't so dramatic, but exists. See: mx1# doveadm fetch -u kir...@korins.ky 'uid' mailbox virtual.All | grep '^uid:' | tail -n 5 uid: 145485 uid: 145486 uid: 145487 uid: 145488 uid: 145489 mx1# doveadm fetch -u kir...@korins.ky hdr.Message-ID mailbox virtual.All uid 145489 hdr.message-id: <cadguc0gtckctzwpdwf4xyu63ozzjzycqmiuzgsuoeoz6gop...@mail.gmail.com> mx1# vs mx2# doveadm fetch -u kir...@korins.ky 'uid' mailbox virtual.All | grep '^uid:' | tail -n 5 uid: 145487 uid: 145488 uid: 145489 uid: 145490 uid: 145491 mx2# doveadm fetch -u kir...@korins.ky hdr.Message-ID mailbox virtual.All uid 145491 hdr.message-id: <cadguc0gtckctzwpdwf4xyu63ozzjzycqmiuzgsuoeoz6gop...@mail.gmail.com> mx2# doveadm fetch -u kir...@korins.ky hdr.Message-ID mailbox virtual.All uid 145489 hdr.message-id: <87edd58shf.wl-kir...@korins.ky> mx2# So, by some digging I discovered the mails which triggers an issue: mx1# doveadm fetch -u kir...@korins.ky 'uid' mailbox virtual.All | grep '^uid: 14484' uid: 14484 uid: 144840 uid: 144841 uid: 144845 uid: 144848 uid: 144849 mx1# doveadm fetch -u kir...@korins.ky hdr mailbox virtual.All uid 144841 | md5 d65a22e12bd0c72d321a78d2efd3383b mx1# doveadm fetch -u kir...@korins.ky hdr mailbox virtual.All uid 144840 | md5 25a8b53ecfd513cf9031dae0e9000d92 mx1# vs mx2# doveadm fetch -u kir...@korins.ky 'uid' mailbox virtual.All | grep '^uid: 14484' uid: 14484 uid: 144840 uid: 144842 uid: 144846 uid: 144849 mx2# doveadm fetch -u kir...@korins.ky hdr mailbox virtual.All uid 144842 | md5 d65a22e12bd0c72d321a78d2efd3383b mx2# doveadm fetch -u kir...@korins.ky hdr mailbox virtual.All uid 144840 | md5 25a8b53ecfd513cf9031dae0e9000d92 mx2# this email 144841 / 144842 were delivered to mx1 at 17 Feb 2024 17:52:18 which allows me do check logs: mx1# zgrep '17:52:[123]' /var/log/maillog.3.gz Feb 17 17:52:15 mx1 smtpd[52094]: d7da603e4213f8ff smtp connected address=199.185.178.25 host=mail.openbsd.org Feb 17 17:52:15 mx1 smtpd[39991]: dnsbl: d7da603e4213f8ff DNS error 2 on cbl.abuseat.org Feb 17 17:52:17 mx1 smtpd[52094]: d7da603e4213f8ff smtp tls ciphers=TLSv1.3:TLS_AES_256_GCM_SHA384:256 Feb 17 17:52:18 mx1 smtpd[52094]: d7da603e4213f8ff smtp message msgid=d8e3748c size=4552 nrcpt=1 proto=ESMTP Feb 17 17:52:18 mx1 smtpd[52094]: d7da603e4213f8ff smtp envelope evpid=d8e3748cc73371ec from=<owner-ports+m141...@openbsd.org> to=<kir...@korins.ky> Feb 17 17:52:19 mx1 dovecot: lmtp(15471): Connect from local Feb 17 17:52:19 mx1 dovecot: lmtp(kir...@korins.ky)<15471><h2dQAEPk0GVvPAAAeeMcAQ>: sieve: msgid=<4bc76d19-00f2-b60b-a87f-315adfd08...@grey.my.domain>: stored mail into mailbox 'INBOX' Feb 17 17:52:19 mx1 dovecot: lmtp(15471): Disconnect from local: Logged out (state=READY) Feb 17 17:52:19 mx1 smtpd[52094]: d7da603f60cff302 mda delivery evpid=d8e3748cc73371ec from=<owner-ports+m141...@openbsd.org> to=<kir...@korins.ky> rcpt=<kir...@korins.ky> user=vmail delay=1s result=Ok stat=Delivered Feb 17 17:52:19 mx1 smtpd[52094]: d7da603e4213f8ff smtp disconnected reason=quit mx1# nothing, let check mx2: mx2# zgrep '17:52:[123]' /var/log/maillog.3.gz Feb 17 17:52:17 mx2 smtpd[3556]: 99938cb221b4cb0b smtp connected address=199.185.178.25 host=mail.openbsd.org Feb 17 17:52:20 mx2 smtpd[3556]: 99938cb221b4cb0b smtp tls ciphers=TLSv1.3:TLS_AES_256_GCM_SHA384:256 Feb 17 17:52:30 mx2 smtpd[3556]: 99938cb221b4cb0b smtp disconnected reason=quit mx2# nothing as well. I do have full sync each 15 minutes, let check any dsync logs on bigger interval (an hour): mx1# zgrep '17 1[78]:' /var/log/maillog.3.gz | grep dsync mx1# and mx2# zgrep '17 1[78]:' /var/log/maillog.3.gz | grep dsync mx2# Also hasn't got anything. It seems that SSH based replication is better than TCP, and both of at least works that I can't say about TCPS. But it may introduce a kind of collision inside virtual boxes. So, to future investigate an issue I've started to run dsync-server as: doveadm -Dv dsync-server, I hoep that it allows to catch this. And as usual re-created vurtial boxes. -- wbr, Kirill _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
