i use Zimbra Client (Zimbra Desktop) on Windows 7. I use this Client several mounth for a Pop3 Account. Now, the Provider has change the Server-Plattform. I would change the new Account infos in the Client, but i alway become the Messeage:

Verbindung zu "pop.name.domain.ext:110" kann nicht hergestellt werden. Prüfen Sie Host/Port und Netzwerkkonnektivität.

I has test it with several other Mail-Accounts from other Servers (IMAP, Google, etc), but alwas is the same Message (:143, :110).

Has anyone a idea, what's my problem?

Many Thanks.
