iPhone and Android with Zimbra Mobile PB

[KamZor]

Hello,

I have a redhat distribution with ZCS trial license (60 days), registered and activated.
My DNS is correctly configured (direct and reverse zone Ok, and mx entry is resolved well too)

My problem come when i try to configure the Exchange account in my iphone4 (and on a Samsung galaxy S too).

I got the error (french translated) : "Impossible to check mails. The connexion to the server couldn't be established".

Do someone have an idea

The problem was located in the default timeout in iPhone Connexion.
There's an Apple patch that solved my pb :

iOS 4.0: Exchange Mail, Contacts, or Calendars may not sync after update
