Exchange Server 2010 - Cant receive external emails

Hi Everyone

I have a Server 2008 R2 Exchange Server running 2010. I am having issues receiving emails form external. I can send and receive fine internally and I can send fine externally. I have setup receive connectors and also my MX records are correct and I have forwarded ports 25, 80 and 443 to the server. However I am still not receiving external emails.

Please help

Thanks

Test exchange connectivity here: https://testconnectivity.microsoft.com/

Also, check the services on the server to make sure the appropriate exchange related services are started, notably for hub (or edge) transport.

Are you running low (less than 10% free) on any volumes?

Please have a read of my article to see if you are suffering from Backpressure which will cause inbound mailflow to stop:
