FOLLOW THESE STEPS

Connect the mailbox securely

Work through each step in order. Keep this guide open in another tab if that is easier.

  1. 1

    Open Mail account settings

    Open Settings, choose Apps, Mail, Mail Accounts and Add Account. On older iOS versions the route may be Settings, Mail, Accounts and Add Account.

    • Tap Other.
    • Tap Add Mail Account.
    • Enter your name, full email address, mailbox password and a useful description.
  2. 2

    Choose IMAP

    Select IMAP at the top of the New Account screen. IMAP keeps the same folders and read status across Apple Mail, webmail and other devices.

  3. 3

    Complete Incoming Mail Server

    Use the assigned hostname displayed under Connect your email in Knox.

    • Host Name: your assigned mail server.
    • User Name: your full email address.
    • Password: the mailbox password.
  4. 4

    Complete Outgoing Mail Server

    Apple labels some fields optional, but the username and password are required for oXnames SMTP authentication.

    • Host Name: your assigned mail server.
    • User Name: your full email address.
    • Password: the mailbox password.
  5. 5

    Save and verify the ports

    Tap Next and Save. If you need to check the advanced settings, use IMAP port 993 with SSL and SMTP port 587 with STARTTLS, or SMTP port 465 with SSL.

    • Do not continue through a certificate warning.
    • Make sure Use SSL is enabled.
    • Keep Server Port set to the secure value.
  6. 6

    Test Apple Mail

    Open Mail, select the new account and send a message to another address. Reply to that message and check that it arrives on the iPhone.

WHAT HAPPENS NEXT

Check that it worked

Apple Mail verifies the account and begins synchronising the Inbox, Sent and other IMAP folders.

IF IT DOES NOT LOOK RIGHT

Try this before contacting support

If Apple Mail says the username or password is incorrect, re-enter the full email address in both username fields. If it cannot verify the server, compare the hostname with Knox and confirm SSL is enabled.

COMMON QUESTIONS

Answers before you get stuck

Why does iPhone say Cannot Verify Server Identity?

Stop rather than accepting the warning. Check that the hostname exactly matches the assigned server in Knox and that the device date and time are correct.

Why does Apple show SMTP username as optional?

It is optional for some providers, but oXnames SMTP requires authentication. Enter the full email address and mailbox password.

Will deleting a message on iPhone delete it elsewhere?

With IMAP, changes synchronise with the server. A deleted message will normally move to Trash and that change appears in webmail and other connected devices.

Interface wording can change after application updates. See Apple iPhone and iPad Mail setup guidance alongside the oXnames settings above.
