A PHP API for retrieving Mail From Yahoo, GMail, Hotmail

Question

There are a few APIs for grabbing the address book/contact list from the major providers of email.

I was wondering do APIs like this exist for grabbing emails/messages received?

Thanks all

EDIT

I am sure I can do this myself. However, I don't want to "re-invent" the wheel if someone has done it already. Probably better than I can since I am just a noob :P

I think all of this services provide POP/IMAP protocol which you can acces with PHP's functions: http://php.net/book.imap
