I use "Release 6.0.7_GA_2473.UBUNTU8 UBUNTU8 NETWORK edition".

I turned on the "Zimbra Mobile" option in the Admin UI and tried to connect to Zimbra with iPhone4G (iOS 4).

Mail address: testiphone@mydomain.local
Domain: mydomain.local
Useraccount: testiphone
PW: **************
MailServer: zimbra.mydomain.local

After this I get something like this:
"Exchange account verfication failed"
This seems to be an SSL problem.

So I ignored the message and saved the account. I turned of the SSL option in the "Account Information" on the iPhone. After that no message appear.

But checking mails or sending mails does not work. I get an error.
Is there something special that I have to check first?
