Hi Danke dir ich glaube ich wurde vorhin selbst fündig.
Ich bin der Anleitung System > Konfiguration > SMTP Postifx with dovecot gefolgt neustart war erfolgreich doch bei Mail dovecot postfix wird es nicht neu gestartet.
Ich bin exakt nach der Anleitung gegangen und nachdem ich versucht habe mail dovecot postfix neuzustarten bekam ich folgende fehlermeldung: Job for dovecot.service failed because the control process exited with error code.
See "systemctl status dovecot.service" and "journalctl -xeu dovecot.service" for details.
