Create new dedicated receive connector for relay and add the IP address of  sharepoint  server under network Tab.

Hello,<br />
<br />
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.<br />
<br />
Get-ReceiveConnector &lt;RelayName&gt; | Add-ADPermission –User “NT Authority\Anonymous Logon” –ExtendedRights ms-Exch-SMTP- Accept-Any-Recipient,ms-ex<wbr />ch-bypass-<wbr />anti-spam<br />
<br />
It will take some time to replicate depend upon active directory topology.<br />

Hello,

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.

Unable to  Relay

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Server Software

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
