Remember that, if you have an Enhanced account, you can use ActiveSync, to not only sync e-mails, but also contacts and events.
Also note that you can log on to Afterlogic WebMail from your iOS device and it shall offer an automated way (profile) of setting up e-mail as IMAP, along with calendars and contacts (CalDAV/CardDAV).
Here's the step by step for setting up an IMAP account on iOS.
Note that IMAP is preferred over POP. If you want to set up the account as POP, you have to set it up manually. IMAP is a protocol made to support several devices accessing one same account, with all folders synced at our server, which also guarantees that our backups will be executed.
