Hallo ich habe hier im Forum Support gehabt, um meinen Postfix Mailserver zum laufen zu bringen. Das funktionierte auch noch bis gestern.
Ich habe heute meinen Domainnamen in "sulix" geändert und diese Änderung auch in der main.cf eingetragen. Aber das Problem hab ich eigentlich seit dieser Änderung.
Nach absenden einer Mail gibt mir der Befehl: "tail -f /var/log/mail" folgende Fehlermeldung:
