I have managed to build a mail server with exchange 2010. configuration that I use is still the default. to send mail has been successful, but still can not receive email.

as info, when I put on the exchange server in local network with other workstations, the local IP 10.80.136.202. And public IP 202.171.x.x

We also have a Firewall ASA 5505, with a configuration like this:

On the Default Receive connector Properties,
Select the permission tab and check the Anonymous Users.

This will allow the Exchang 2007 organization to receive the mails from Internet.
