I'm new to zimbra, so apologies if it's a siily question.
I tried to add my Zimbra account on an Iphone 3G.

Adding an "exchange" account,
Adress blabla@toto.com
Domain mail.toto.com
user blabla@toto.com
pwd yeahright
desc. my zimaccount

There's no SSL on/off slide available (as described in the Zimbra :: Wiki).
I validate, it's trying to sync then appears a "server" field. I can't leave it blank so I tried the same mail.toto.com but it runs "checking" for while then I get a message telling me it cannot check details.

Any idea anyone?
