Not sure if this is a Dovecot or Postfix issue we use Dovecot for authentication for Postfix. Mailboxes are stored in MySQL.
Have noticed this today: auth-worker(42777): Info: sql(cont...@com.au,127.0.0.1): unknown user (given password: someone123) Also i...@com.au etc. They are coming through on port 465. Obviously my domain is not ‘com.au’ - how can I stop these attempts from even being considered? I did update to Postfix 3.4.5 yesterday. Running Dovecot 2.3.5. Thanks, James.
