As long a it supports POP or IMAP which I know gmail does, as I use gmail on my thunderbird client. I think Hotmail and Yahoo do too, not too sure about AOL though.
Can you add Hotmail, Yahoo!, AOL, and Gmail accounts to Firebird?
Mozilla thunderbird is also a very nice and very simple program for mails.Here take a look:

Try using the Webmail extension. it takes a tiny bit of configuration but Prefer it over my hotmails pop service
