Durch Zufall sah ich - als ich postfix mehr oder weniger aus Versehen 
von der command line startete 'postfix" - daß es
eine Warnung gab:
/usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: 
smtdp_delay_reject=yes

Ich fand die in keinem log.

Zu welcher Option gehört sie - muß was mit dem initial SMTP-Dialog zu 
tun haben und wann eine Mail abgewiesen wird.
( so eine Art "look ahead" ?)
