GCG_admin -> emails bouncing back to senders and no mail being recieved (28.Jun.2011 10:06:46 AM)


I have read previous threads and can't seem to find the solution.

I am running an Exchange Server 2010 on a Server 2008 R2. I have a BT Broadband Connection with a firewalled router and my domain hosted with a hosting company.My Exchange Server was set up by an IT Consultant who I can't get hold of anymore. This is a new installation and no previous server existed.

I can send inbound mail but cannot recieve any mail. BT told me my router IP address which I gave to my domain hosting company who set up a pointer. I cannot recieve any mail now via pop email or exchange. Emails are being bounced back from apparantley my server. Snippet is below. I have run the Exchange Connectivity Tools and some errors come up which I dont know how to resolve. Please can someone give me a step by step fix guide as I am losing a lot of important emails.

You need to modify the receive connector - see step # 2 here:
