It's just like the others said, create a new connector (if the other/old one is not needed anymore, remove it) sometimes/somehow (what ive experienced myself) the receive connector has lost its way.
is exchange configured to accept mails / connections coming from those ip's / servers on the receive connector?
Gaurav SinghSolution ArchitectAuthor Commented:
Yes its configured
Mohammed TahirCommented:
Create new dedicated receive connector for relay and add the IP address of  sharepoint  server under network Tab.
Sanjay SantokiCommented:

You simply need to create a new connector and need to give permission to anonymous user. Then just add only Sharepoint servers IP address to that connector on the network tab.

Get-ReceiveConnector <RelayName> | Add-ADPermission –User “NT Authority\Anonymous Logon” –ExtendedRights ms-Exch-SMTP- Accept-Any-Recipient,ms-exch-bypass-anti-spam

It will take some time to replicate depend upon active directory topology.
