I've been trying to log into Dovecot without success, and this is what I found in /var/log/mail.log:

Jan 3 02:47:33 grace dovecot: auth: Debug: client passdb out: FAIL#0111#011user=me@mydomain.com Jan 3 02:47:33 grace dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=me@mydomain.com, method=PLAIN, rip=192.168.1.1, lip=192.168.1.10, TLS, session=<bgBsu6jUhqzAqAEB>

I know I provided the correct password, but I'm still having no joy.
