PopMan

I have two accounts at directbox, one going on "@cloudmail.de", the other going on "@directbox.de". The POP/IMAP settings for both endings are the same. The cloudmail.de-account as per today gives a "Zeitüberschreitung" error, the direcbox.de account seeem to work normal. No changes from my side. What could cause this?

Could someone please answer? The problem still persists. Sometimes like right now, instead of Zeitüberschreitung it says Ungültige Serverantwort Error 903.
