Postfix SMTP server: errors from unknown[45.144.212.169]
Unfortunately for above session, log contains only:
Mar 6 08:13:34 goniec postfix/smtp/smtpd[75863]: connect from
unknown[45.144.212.169]
Mar 6 08:13:34 goniec postfix/smtp/smtpd[75863]: disconnect from
unknown[45.144.212.169] ehlo=1 auth=0/1 quit=1 commands=2/3
The expected result would be like for the following session (at least line with IP and helo).

Reason behind is script validating helo/ehlo and scoring IP addresses for temporary block.
