iOS for iPhone/iPad/iPod and MacOS Mail.app for Mountain Lion (10.8+) can be configured by downloading any one of the two desired protocols from your mail client setup screen and following this step:
- If you are prompted to open, run, or save this file, choose “Run” or “Open”.
- If your computer asks if you would like to enter the information into the registry, choose “Yes”.
- Use your email account password as the password.
Please Note: IMAP Path Prefix must be set to INBOX; otherwise, Mail.app® will not be able to store deleted, draft, or sent mail on the server.
You can also set it up manually by entering the details as provided in cPanel > Email Accounts > Setup Mail Client.
