I have been running cyrus imap successfully for some years. Suddenly the server is throwing 'User unknown' in the maillog. I can login using using Thunderbird Mail OK, but NOTHING is being delivered to any user, pecifically to me brad@xxxxxxxxxxxxxxxxxxxxx I am at a complete loss to understand what has gone wrong. How do I diagnose the problem? What in detail is mechanism that decides that a user is known/unknown? I have included what I think are the relevant messages and parts of my configuration files (sendmail.mc cyrus.conf) files (sorry about the length) My tests while logged in to the server as brad: [brad@dell2600-1 ~]$ hostname dell2600-1.bradcan.homelinux.com [brad@dell2600-1 ~]$ sendmail brad@xxxxxxxxxxxxxxxxxxxxx < email.txt <<<<< THIS FAILS see below As root maillog content following the above: [root@dell2600-1 brad]# cat /var/log/maillog Nov 27 15:18:35 dell2600-1 sendmail[4798]: wARFIZXZ004798: from=brad, size=44, class=0, nrcpts=1, msgid=<201811271518.wARFIZXZ004798@xxxxxxxxxxxxxxxxxxxxx>, relay=brad@localhost Nov 27 15:18:35 dell2600-1 sendmail[4799]: NOQUEUE: connect from localhost.localdomain [127.0.0.1] Nov 27 15:18:35 dell2600-1 sendmail[4799]: AUTH: available mech=CRAM-MD5 DIGEST-MD5, allowed mech=EXTERNAL DIGEST-MD5 CRAM-MD5 Nov 27 15:18:35 dell2600-1 sendmail[4799]: wARFIZvg004799: Milter: no active filter Nov 27 15:18:35 dell2600-1 sendmail[4799]: STARTTLS=server, relay=localhost.localdomain [127.0.0.1], version=TLSv1/SSLv3, verify=NO, cipher=DHE RSA-AES256-GCM-SHA384, bits=256/256 Nov 27 15:18:35 dell2600-1 sendmail[4799]: STARTTLS=server, cert-subject=, cert-issuer=, verifymsg=ok Nov 27 15:18:35 dell2600-1 sendmail[4798]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-GCM-SHA384, bits=256/256 Nov 27 15:18:35 dell2600-1 sendmail[4799]: AUTH: available mech=CRAM-MD5 DIGEST-MD5, allowed mech=EXTERNAL DIGEST-MD5 CRAM-MD5 Nov 27 15:18:35 dell2600-1 sendmail[4799]: ruleset=trust_auth, arg1=brad@xxxxxxxxxxxxxxxxxxxxx, relay=localhost.localdomain [127.0.0.1], reject=550 5.7.1 <brad@xxxxxxxxxxxxxxxxxxxxx>... not authenticated Nov 27 15:18:35 dell2600-1 sendmail[4799]: wARFIZvh004799: from=<brad@xxxxxxxxxxxxxxxxxxxxx>, size=358, class=0, nrcpts=1, msgid=<201811271518.wARFIZXZ004798@xxxxxxxxxxxxxxxxxxxxx>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Nov 27 15:18:36 dell2600-1 sendmail[4798]: wARFIZXZ004798: to=brad@xxxxxxxxxxxxxxxxxxxxx, ctladdr=brad (500/500), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=30044, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (wARFIZvh004799 Message accepted for delivery) Nov 27 15:18:36 dell2600-1 sendmail[4801]: AUTH=client, relay=localhost, mech=, bits=0 Nov 27 15:18:36 dell2600-1 sendmail[4801]: wARFIZvh004799: to=<brad@xxxxxxxxxxxxxxxxxxxxx>, delay=00:00:01, xdelay=00:00:00, mailer=cyrusv2, pri=120358, relay=localhost, dsn=5.1.1, stat=User unknown Nov 27 15:18:36 dell2600-1 sendmail[4801]: wARFIZvh004799: wARFIavg004801: DSN: User unknown Nov 27 15:18:36 dell2600-1 sendmail[4801]: wARFIavg004801: to=<brad@xxxxxxxxxxxxxxxxxxxxx>, delay=00:00:00, xdelay=00:00:00, mailer=cyrusv2, pri=31677, relay=localhost [[UNIX: /var/lib/imap/socket/lmtp]], dsn=5.1.1, stat=User unknown ~ o ~ What cyradmin says: localhost.localdomain> ver name : Cyrus IMAPD version : v2.4.17-Invoca-RPM-2.4.17-7.el6 d1df8aff 2012-12-01 vendor : Project Cyrus support-url: http://www.cyrusimap.org os : Linux os-version : 2.6.32-754.6.3.el6.i686 environment: Built w/Cyrus SASL 2.1.23 Running w/Cyrus SASL 2.1.23 Built w/OpenSSL 1.0.1e-fips 11 Feb 2013 Running w/OpenSSL 1.0.1e-fips 11 Feb 2013 Built w/zlib 1.2.3 Running w/zlib 1.2.3 CMU Sieve 2.4 mmap = shared lock = fcntl nonblock = fcntl idle = idled localhost.localdomain> info user/brad@xxxxxxxxxxxxxxxxxxxxx {user/brad@xxxxxxxxxxxxxxxxxxxxx}: duplicatedeliver: false lastpop: 24-Oct-2013 21:04:43 +0100 lastupdate: 27-Nov-2018 04:00:00 +0000 partition: default pop3newuidl: true sharedseen: false size: 8489796 ~ o ~ Part of /etc/mail/sendmail.mc ...
