Set-ReceiveConnector -Identity "Servername\Relay" -PermissionGroups "AnonymousUsers"

One Exchange Management Shell – Run

Get-ReceiveConnector "Relay Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

For Example –

Get-ReceiveConnector "ServerName\RelayConnectorname" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

Now that Application will be able to relay through Exchange 2013 with ease.
