For those of you who are using AOL as your email account, AOL has finally opened up its mail servers to use outside of their own programs using IMAP protocol (so you can use it with Outlook, Outlook Express, Thunderbird, etc.).
server type is IMAP4 (not POP3).
The incoming server is imap.aol.com. The outgoing server is smtp.aol.com (you must change the port from 25 to 587).
