Hi, when an user inputs an incorrect password, I have the following message in the logs:

mx1 postfix/smtpd[1069]: warning: unknown[89.xx.xx.xx]: SASL LOGIN authentication failed: UGFzc3dvcmQ6

Which is perfectly normal.

But how can I also show the username in the logs? I want to see which user keeps entering the wrong password...

Thanks!

How about append IP address of this client in Postfix parameter "debug_peer_list" (and reload Postfix service)? It will log debug messages includes smtp username.

But obviously, you have to do this manually. sad
