Mail won't work with .Mac

Hello, I've been having a problem with Mail and my .Mac account. Mail will receive my emails from .Mac but it won't send any... Can anyone tell me how to configure Mail to send emails... I think it's a problem with the selected server or something.
Thanks.

What is the out going mail server for .mac?

Incoming server: mail.mac.com

Outgoing server:
smtp.mac.com

Use Secure Sockets Layer (SSL)
authentication: password

Thank you, now it works... For some reason, it was set as a POP account on mine.

No problem...
