Detecting email on server

I am trying to make a program like the Yahoo Pager(c) program that tells you when you have mail in your email account. The user will tell the program their username and password and it will idle until a email message is send to them.

Any idea how I can do this?

Thanks,

What you will want to look at is the POP3 protocol specification (RFC 1460). You will want to periodically connect to the users POP3 server and check if any new mail has arrived.

Thanks, but how do I connect to the pop3? Can you give me sometype of example?

Thanks,
