Hello!
# postconf mail_version
mail_version = 2.11.3
I have this in my log this morning:
Sep 5 08:05:46 bitmachine1 postfix/smtpd[7475]: NOQUEUE: reject: RCPT from
unknown[14.215.136.46]: 454 4.7.1 <xiaonanzi11...@163.com>: Relay access
denied; from=<vy...@nimmini.de> to=<xiaonanzi11...@163.com> proto=ESMTP

Sep 5 08:05:49 bitmachine1 postfix/smtpd[7475]: too many errors after DATA
from unknown[14.215.136.46]
How can I change the temporary 454 to a 5xx reject?
I dont find anything in the main.cf regarding this.

outputs nothing.
I'm a bit helpless with this one.
