Hallo,
seit gestern kann eM Client keine Verbindung zum Telekom Servier aufbauen.
Meine Einstellungen wurden nicht verändert -
kann es wegen der Umstellung seitens Telekom auf TLS 1.2 / 1.3 sein ?
Folgende Einstellungen habe ich :
IMAP : Port 993 - SSL/TLS auf bestimmten Ports verwenden (Legacy)
SMPT : Port 587 - SSL/TLS auf bestimmten Ports verwenden (Legacy)
Wie gesagt bis vorgestern klappte noch alles.
Mit einem anderen Provider geht eM Client noch.
Bei der Telekom kann ich mich einloggen und Mail senden und empfangen, scheinbar liegt es also bei eM Client.
Viren Programm deaktiviert + Firewall - keine Besserung
Voran kann es liegen ?
Gruß
Andreas
