Geschafft!
Hier die Lösung:
1) Beim Zertifikat muss "bluewin.ch" angegeben werden
2) UserID und Passwort müssen Base64 encoded angegeben werden (Encoden über diese Webseite möglich: https://www.base64encode.org/) Oben Klartext rein, PB ENCODE drücken, unten kommt das Ergebnis raus.
3) in der Funktion readResponse muss unbedingt ein Delay von 1000 (=1 Sec) angegeben werden, damit der Mailserver nachkommt.
Hier das Ergebnis und die Lösung:
