I am attempting to sign into my email account via my android and after I enter my email address and password it asks me to select "POP 3", "IMAP", or "Exchange". I have no idea what I am doing and would love to have some help in figuring this out. My email address is firstname.lastname@example.org in case that information is needed to help me out. I use that email as well as a yahoo email. Also do not know if that information was needed but figured I better give as much information beforehand. Also after I get past this selection, will I have more that I have no idea about?
