Hi, we recently upgraded to 2.3.13 from 2.3.11 and the log format for auth errors seems to have change. This change may have an adverse effect on fail2ban rules.

Is there a way to revert to old format ?

Thank you !

Old log example: Jan 10 00:32:37 mail dovecot: auth-worker(50806): sql(name@domain,112.18.92.0.104,): Password mismatch Jan 10 03:20:02 mail dovecot: auth-worker(26057): sql(name@domain,112.18.92.0.104,<oMyxloG4M7AFt1xo>): Password mismatch

New log example:

Jan 10 00:32:37 mail dovecot: auth-worker(50806): conn unix:auth-worker (pid=22503,uid=0): auth-worker<585236>: sql(name@domain,112.18.92.0.104,): Password mismatch Jan 10 03:20:02 mail dovecot: auth-worker(26057): conn unix:auth-worker (pid=25928,uid=0): auth-worker<4234337>: sql(name@domain,112.18.92.0.104,<oMyxloG4M7AFt1xo>): Password mismatch
