What information do you need in order to configure a mail account on an iOS device?

What will be an ideal response?

If your email account is with iCloud, Microsoft Exchange, Google, Yahoo!, AOL, or Outlook, your email address and password are all you need because the iOS can automatically set up these accounts. Otherwise, you will need the names of your incoming and outgoing e-mail servers. You'll also need to know the type of protocol your incoming server uses. Finally, you'll require the security configuration details necessary to connect to the mail server.
