suddenly 'User unknown'?

Wed Nov 28 19:46:49 EST 2018

Hi Dan, thanks for the prompt reply. Not sure if I should reply to the
list or direct to you.

lm user/brad at bradcan.homelinux.com                      
user/brad at bradcan.homelinux.com (\HasChildren)

and the directory
/var/spool/imap/domain/b/bradcan.homelinux.com/b/user/brad exists and is
intact.

Sorry I don't I'm not sure about cyrus syslog configuration:

 I have this in rsyslog.conf:

# cyrus imapd
auth.*                            /var/log/auth.log

So I assume auth.log  has the log entries you ask for. Here it is:

Perhaps I should change my rsyslog configuration.
https://cyrusimap.org/imap/installing.html has some alternative
instructions.

Will the following be more helpful?

    |local6.*        /var/log/imapd.log|

    |auth.debug      /var/log/auth.log|
