Re: Kein Versand von Push-Mails von Fritzbox möglich

Ich hoffe mal die Antwort klappt, habe aus Versehen nur die 
Zusammenfassung ausgewählt und damit keine E-Mail auf die ich direkt 
antworten kann :/

Erstmal danke für die schnelle Rückmeldung! Es handelt sich um die 
Fritz!Box 7590 mit dem 7.11 OS, also alles aktuell.

Mit der Test-Mailbox von André (die ja scheinbar auch auf mailcow 
basiert) hat der Versand ohne Probleme geklappt, allerdings bietet sie 
mir auch weitaus mehr Ciphers an. Ich habe sie zur Übersicht beide in 
den Anhang gepackt, dabei ist mir aufgefallen, dass meine Konfiguration 
mit der vorher verlinkten main.cf lediglich Ciphers mit elliptischen 
Kurven anbietet. Das ist zwar modern und sicher, entspricht aber nicht 
dem, was die Fritz!Box anbietet. Wenn ich den tcpdump im Anhang richtig 
interpretiere kann die Box nur Ciphers mit RSA, bin aber kein 
Verschlüsselungsexperte.
