- Open Settings › Apps › Mail › Mail Accounts › Add Account (on older iOS versions: Settings › Mail › Accounts › Add Account).
- Tap Other › Add Mail Account.
- Enter your name, full email address, password and a description, then tap Next.
- Make sure IMAP is selected at the top.
- Under both Incoming Mail Server and Outgoing Mail Server, enter:
- Host name: your server hostname (or mail.yourdomain.co.uk)
- User name: your full email address
- Password: your mailbox password
- Tap Next, wait for the account to verify, then tap Save.
If it won't verify
Go back to the account settings and check:
- Incoming: SSL on, port 993
- Outgoing (SMTP): SSL on, port 465, authentication Password
Using your server hostname instead of mail.yourdomain.co.uk avoids certificate warnings.
