Not receiving emails from internet on Exchange 2010 SP1 Help!

Hi all,

On the last 15 day I have encountered problems receiving emails from the internet. I have updated to Exchange 2010 SP1 over a month ago and install SP1 Rollup 1 and 2. I have not touch the server configuration and it just stopped working. I’m able to test the server for connectivity using mxtoolbox I’m also able to send emails outside of my organization and send and receive internally.

Here is my receive connector config:
