E-Mail Verbindung klappt nicht

Hallo,

mittlerweile habe ich auf einer neuen VM (Windows, auf Ubuntu gab’s auch wieder Probleme) auch die Installation hinbekommen und das Programm läuft. Jetzt taucht allerdings das nächste Problem auf. Ich habe bei meinem Nutzer die E-Mail-Einstellungen vorgenommen. Sowohl wenn ich beim Posteingangsserver SSL anhake als auch wenn ich es nicht tu, kommt jeweils eine Fehlermeldung. Im Fall von SSL abgehakt kommt „No login method supported“, im anderen Fall „Keine Verbindung zum Mailserver: Remote host closed connection during handshake“.

Das Log hierzu lautet:

Das sind die providerseitig vorzunehmenden Einstellungen:

Gibt es hierzu eine Lösung?
