Most POP3 accounts you are going to have to pay for. THe only thing I can suggest if you are looking for a free solution is get yourself one of those freewebsites. Usually they come with banners all over yoursite but atleast you will get the pop3 stuff.
www.bluegenesis.com has some cheap site options, if you buy something from then and they have a reference area tell them that
www.zeora.com referenced you!
