Hi
i m using on my server postfix-3.5.8 and cyrus-sasl-2.1.27
I m using fail2ban too to prevent brute force attack.
my problem is that when a connection failed because of wrong password i
don't know what account is targeted
the line is
Oct 5 11:07:52 hermes postfix/smtpd[277411]: warning:
unknown[122.179.129.110]: SASL LOGIN authentication failed:
authentication failure
There s no username logged.
Is there a way to log this username?
