[postfix-users] reject mit 450

[Margrit Lottmann]

Auf unseren Relay-Servern weise ich zuviel Empfaenger falsch ab ...aber 
nur mit  4.5.0

Der einliefernde Server kommt dann immer wieder, bis ich ihn mit

too many errors after data erst mal stoppe

log-Beispiel:
::::::::::::

Jun 25 06:03:56 mx2 postfix/smtpd[19843]: NOQUEUE: reject: RCPT from 
sunny.urz.uni-magdeburg.de[141.44.8.7]: 450 4.1.2 
<karin.ludwig at googlemail.de>:
  Recipient address rejected: Domain not found; from=<alumni at ovgu.de> 
to=<karin.ludwig at googlemail.de> proto=ESMTP 
helo=<sunny.urz.uni-magdeburg.de>

conf-Auszug zu reject-Optionen
::::::::::::::::::::::::::::::

Kann ich es ueberhaupt wagen, bei recipient-fehlern, die nicht unsere
Aliasse betreffen, "hard" zu rejecten ???
