Configuration problems with IMAP e-mail on iOS with a non-standard SSL port.

Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.
