auth error log format change

[Adrian Minta]

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 at domain,112.18.92.0.104,<Dg/+P3+49cMFt1xo>): Password mismatch
Jan 10 03:20:02 mail dovecot: auth-worker(26057): 
sql(name at 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 at domain,112.18.92.0.104,<Dg/+P3+49cMFt1xo>): 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 at domain,112.18.92.0.104,<oMyxloG4M7AFt1xo>): Password mismatch
