This is a PROTOCOL ERROR because Postfix did not announce AUTH
support. It is not a policy violation.
As a matter of principle, Postfix does not log PROTOCCOL ERRORS
because that would be a 100x multiplier (a snall input results in
o(100) bytes being logged. Unlike errors, Postfix does log policy
violations.
Of course, sending an email transcript also multiples the volume,
but email transcripts are disabled by default.
However, Postfix does log command statistics:
> 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
There, you can see that an AUTH command was rejected.
Generally,
grep '=[0-9]*/' /var/log/maillog
will show all sessions that contained a failed command, because
either the client made an error, or because Postfix did not accept
the command for some reason (policy, out of space, etc.).
