iPhone IMAP (or POP) setup. Not receiving mail at all...

Hello

I have recently signed up for zoho mail and have not been able to find a solution to my problem in the forums or any help documents. I am using the iphone 3gs native mail client.

I eventually managed to create the account and IMAP is enabled in my zoho settings area, however when I try to access mail on my iphone, the status cycles through:

Updated Date & Time -> Connecting -> Checking Mail -> Downloading 1 of 4 (progress bar does not progress) -> and then cycles back to Updated Date & Time -> Connecting... etc etc

I have triple checked my username and password details, port numbers, incoming and outgoing server names and all correspond to the support documents. I have SSL switched on for both incoming and outgoing.

I am at a loss as to what I can do. I can receive email through other services on my iphone, it is only this account that is not working. No error message either. I can access my mail from a browser on my laptop.

Any assistance is appreciated.
