So I'm trying to add an email account to my iPhone 3G, but it's not a standard email. It is a school email through which my professors email me. I have to log in to my online services (mysierra.sierracollege.edu), and then there is a section of my homepage that has my mail. I've tried doing it but I have no idea what IMAP, SSL, POP, Incoming / Outgoing Mail Server, or anything are specifically, and the differences between them all, so it's hard for me to appropriately set it up. Any help?
