Nach der Änderung der Datei /etc/postfix/main.cf muss der postfix-Dienst neu gestartet werden:
/etc/init.d/postfix restart
Bitte danach den fehlerfreien Betrieb unbedingt testen und Ausgaben in der Datei /var/log/mail bzw. mail.log beobachten !!
Danach kann man die aktuelle Konfiguration abfragen mit dem Befehl
postconfig -n
