[Dovecot] disable auth-worker logging

[Gmail-teopro]

Hello all,

Can someone please give me a hint about how can I disable such messages to
be inserted into log file(maillog this case as syslog_facility = mail)?

>> dovecot: auth-worker(13377): mysql(localhost): Connected to database postfix

All the '_debug' and '_verbose' statements bear the 'no' value.

Thank you.
