/var/log/mail.log gets constantly flooded with Dovecot connect/disconnect messages like this:
Mar 29 18:15:48 summit dovecot: IMAP(email@example.com): Disconnected: Logged out bytes=63/2126 Mar 29 18:15:50 summit dovecot: imap-login: Login: user=<firstname.lastname@example.org>, method=PLAIN, rip=220.127.116.11, lip=18.104.22.168, TLS
These are repeated ad infinitum (to the tune of 11MB of logs per day), and they're obscuring the more important authentication failures and Postfix deliveries/receptions. I've checked Dovecot's wiki page for logging, but no option there stops these messages. Is there any configuration variable I can set within
dovecot.conf to stop these messages being sent to
Clarification: I still want Dovecot to log to
mail.log; I just don't want it logging these frivolous connect/disconnect messages.
