Postfix - Keine ausgehenden Mails möglich

Hallo zusammen,

auf einem Server habe ich das Problem, dass keine Mails nach außen möglich sind.

Der Server erhielt ein Upgrade von Debian 7 auf 8 und anschließend auf Debian 9.

Es läuft Plesk auf dem Server.

Mails untereinander gehen.

Anbei ein Log Auszug:
Code:
Nov 15 17:15:35 mail postfix/smtpd[31411]: connect from unknown[X.X.X.X]

Laut dem Logauszug sieht es danach aus, als wenn beim Senden der Mail keine Authentisierung stattgefunden hat. Wird im Client evtl. Port 25 zu Senden verwendet? Da sollte eigentlich Port 587 (Submission) eingestellt sein oder 465 (SMTPS)
