New Postfix install problem

I just installed Postfix on a Centos system. From an Outlook Client I can send mail wherever I want using the local IP of the Postfix box for the SMTP server in OE. If I use the mail.mydomain.com address it can't find the server. I have an MX record for my server, I have ports 25 and 110 opened in my router, I can ping, mail.mydomain.com. What else is there to turn on?

Thanks for any suggestions
