SMTP 465 offen

MazelaP

Hallo zusammen, 

ich habe in der Einstellung "Listen Interface" nur ein Interface drin.

Leider ist der Port 465 auf allen Interfaces offen.

Warum ist das so und was kann ich tun?

LG

    Hallo Peter,

    (Sorry, my German-speaking brain isn't creating thoughts at the moment. Frowning2)

    Are you sure that port 465 traffic reaches the SMTP Proxy via other interfaces and that it doesn't just go nowhere?  You could always use a DNAT as suggested by #2 in Rulz (last updated 2021-02-16).

    Hi, Bob! 

    Ich habe die Ports von Außen überprüft, alle Interfaces waren über den Port 465 erreichbar.

    Danke für den Tipp mit dem DNAT. Ich habe alle Anfragen geblackholed.

    Trotzdem würde ich gerne wissen, warum diese Ports offen waren.

    Danke!
