Have you forwarded 443/80 from your router to your Exchange server? Have you added the appropriate records to your public DNS? It sounds like you have not. For the Yahoo problems, post the specific NDR. Do you have a reverse DNS entry for your mail server's public IP?

- yes

- i think so, the email is working fine except that i use the public ip address to access my owa instead its computer name
- i hosted my dns in zoneedit, any entry that i have to add/remove
- i'm checking my zoneedit on how to add a reserve dns

If you have to access OWA by IP then something is wrong with your public DNS. Can you post the relevent A records in public DNS for OWA? Basically you should have an A record that resolves your Exchange servers public IP to mail.domain.com (replace mail with whichever host record you want use - should match your Exchange config however).
