[courier-users] NOOP in ESMTP

[Alexei Batyr' <le...@pc...>]

Hi,

Suddenly I encountered that courieresmtpd replies with error 502 to the NOOP
command. It's very strange besause NOOP is the valid command listed in RFC
821.

Jan 15 16:57:02 gateway courieresmtpd: error,relay=194.87.130.2,msg="502
ESMTP command error",cmd: NOOP

Question 2: Why some errors such as 502 above or "DNS violates RFC 1035"
doesn't log at mail.notice level?

Q3 (asked in list by Sergei Mikhailov but not answered yet): Is it possible
to log username along with IP when POP or IMAP login fails?

TIA,
Alexei.
