How to setup my college email to my iphone?

After entering basic information on the first step: Name, Email, Password

it says looking up account, then asks for Incoming Mail Server information: Host name (mail.example.com), followed by User Name (required), then the password is filled in already from the last step.

Then it asks for Outgoing Mail Server information: HostName (smtp.example.com), Username (optional), and password (optional)

Also whether it is IMAP or POP

What do I do?

You should ask somebody
