Simon My original post contained a dump of /var/log/maillog, butwas asked by Dan "what does cyrus syslog say" so assumed there should be some more log messages somewhere. For the record I do: Clear /var/log/maillog then send a test email from the command line. Then /var/log/maillog contains: Nov 29 18:36:51 dell2600-1 sendmail[5067]: wATIapoE005067: from=brad, size=44, class=0, nrcpts=1, msgid=<201811291836.wATIapoE005067@xxxxxxxxxxxxxxxxxxxxx>, relay=brad@localhost Nov 29 18:36:51 dell2600-1 sendmail[5068]: NOQUEUE: connect from localhost.localdomain [127.0.0.1] Nov 29 18:36:51 dell2600-1 sendmail[5068]: AUTH: available mech=CRAM-MD5 DIGEST-MD5, allowed mech=EXTERNAL DIGEST-MD5 CRAM-MD5 Nov 29 18:36:51 dell2600-1 sendmail[5068]: wATIapgq005068: Milter: no active filter Nov 29 18:36:51 dell2600-1 sendmail[5068]: STARTTLS=server, relay=localhost.localdomain [127.0.0.1], version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-GCM-SHA384, bits=256/256 Nov 29 18:36:51 dell2600-1 sendmail[5068]: STARTTLS=server, cert-subject=, cert-issuer=, verifymsg=ok Nov 29 18:36:51 dell2600-1 sendmail[5068]: AUTH: available mech=CRAM-MD5 DIGEST-MD5, allowed mech=EXTERNAL DIGEST-MD5 CRAM-MD5 Nov 29 18:36:51 dell2600-1 sendmail[5067]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-GCM-SHA384, bits=256/256 Nov 29 18:36:51 dell2600-1 sendmail[5068]: ruleset=trust_auth, arg1=brad@xxxxxxxxxxxxxxxxxxxxx, relay=localhost.localdomain [127.0.0.1], reject=550 5.7.1 <brad@xxxxxxxxxxxxxxxxxxxxx>... not authenticated Nov 29 18:36:51 dell2600-1 sendmail[5068]: wATIapgr005068: from=<brad@xxxxxxxxxxxxxxxxxxxxx>, size=358, class=0, nrcpts=1, msgid=<201811291836.wATIapoE005067@xxxxxxxxxxxxxxxxxxxxx>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Nov 29 18:36:51 dell2600-1 sendmail[5070]: AUTH=client, relay=localhost, mech=, bits=0 Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005068: to=<brad@xxxxxxxxxxxxxxxxxxxxx>, delay=00:00:00, xdelay=00:00:00, mailer=cyrusv2, pri=120358, relay=localhost, dsn=5.1.1, stat=User unknown Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005068: wATIapgq005070: DSN: User unknown Nov 29 18:36:51 dell2600-1 sendmail[5067]: wATIapoE005067: to=brad@xxxxxxxxxxxxxxxxxxxxx, ctladdr=brad (500/500), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30044, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (wATIapgr005068 Message accepted for delivery) Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: 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 NOTE: The following is to be expected because both root and postmaster are aliased to brad@xxxxxxxxxxxxxxxxxxxxx Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: alias MAILER-DAEMON => postmaster Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: alias postmaster => root Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: alias root => brad@xxxxxxxxxxxxxxxxxxxxx Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: alias postmaster => root Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: alias root => brad@xxxxxxxxxxxxxxxxxxxxx Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: wATIapgr005070: return to sender: User unknown Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005070: to=brad@xxxxxxxxxxxxxxxxxxxxx, delay=00:00:00, xdelay=00:00:00, mailer=cyrusv2, pri=32701, relay=localhost [[UNIX: /var/lib/imap/socket/lmtp]], dsn=5.1.1, stat=User unknown Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005070: alias MAILER-DAEMON => postmaster Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005070: alias postmaster => root Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005070: alias root => brad@xxxxxxxxxxxxxxxxxxxxx Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgr005070: done; delay=00:00:00, ntries=1 Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: Losing ./qfwATIapgq005070: savemail panic Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: SYSERR(root): savemail: cannot save rejected email anywhere Nov 29 18:36:51 dell2600-1 sendmail[5070]: wATIapgq005070: done; delay=00:00:00, ntries=1 Nov 29 18:36:52 dell2600-1 sendmail[5070]: wATIapgr005068: done; delay=00:00:01, ntries=1 That's the entire content. Now you tell me is cyrus syslog being sent to /var/log/maillog? Or should it be going to /var/imapd.log as the configuration files, man pages and cyrus installation guides ( found here: https://www.cyrusimap.org/imap/installing.html ) say it should? I originally asked for an explanation of the mechanism (IE. sequence of events) lmtp uses to decide stat = 'User unknown" or not. But I seem to be getting deeper and deeper into where the logs are going rather than understanding the process.
