Please can someone assist me. My domain is not receiving email from another domain that is hosted with GoDaddy. They also have their email hosted with GoDaddy. I can send email to them fine. We just cant receive from them. Their server attempts to connect to ours but then for some reason just drops.
Mail flow into my environment:
Internet -> company firewall -> Cisco Ironport -> Exchange 2010 server
On my ironport there are no entries logged for even a connection attempt from their server.
On my firewall however I can see their server attempts to connects but we only receive bytes worth of data, 777, 843, 777, 843. There seems to be a pattern.
Refer to attached image.
