I removed syslog_facility from imapd.conf

Has no effect: present or not, or changed to test.

# /etc/init.d/rsyslog restart

# service sendmail restart

Now when I connect (from another host) using Thunderbird Mail I see in
/etc/maillog:

Nov 30 13:01:02 dell2600-1 sendmail[9865]: NOQUEUE: stopping daemon,

Hum.. cyrus/imaps sends logging to /etc/maillog

I think it is absolutely clear:

1 - where cyrus syslog goes to is a red herring. It goes to, and has
always gone to /var/maillog. It is simply that the prefix 'cyrus' only
appears for cyrus imap transactions and other sendmail is labeled 'sendmail'

2 - imapd is working fine: allows brad.bradcan.homelinux.com to connect
an email client. Also to move email from one mailbox to another. The
proof is that since enabling telemetry logging
/var/lib/imap/log/[email protected]/ reflects imap transactions.

3 - A problem remains with LMTP. as is clearly evident from 'User
unknown' appearing in maillog.

My original question remains: How do I diagnose this when a test email
is sent to [email protected] :

Nov 30 12:59:48 dell2600-1 sendmail[9882]: wAUCxmBS009882:
[email protected], 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

Thanks for your patience.
