What ports have to be opened in firewall to Exchange Server to send and Receive Mail

Hello Experts,

I'd like to know what ports have to be opened in firewall to Exchange Server 2010 to send and receive mail.
I know that I use port smtp to send mail, and what about receiving mail. And Other ports of Exchange that have to be opened?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
