Your/Display name: anything you want

Incoming mail server: mail.yourdomain.com
Outgoing mail server: mail.yourdomain.com
Outgoing mail server does require authentication.
Incoming mail port: 110 for POP3, 143 for IMAP
Outgoing mail port: 25 (If 25 does not work, try 26, as some ISPs block port 25)
** No SSL boxes should be checked **
Note: If you want a secure connection using SSL, please refer to the related article.
Username/Account name: must be the full email address (email@example.com).
Sometimes this setting won't work until you replace the @ with a + in the username.

Warning for iPad users: If you have already setup your email incorrectly, you cannot simply update the settings to be correct. Instead, you need to fully delete the account from the iPad, perform a hard reset, and recreate the entire account with the proper settings.
