23) The configuration from SharePoint side ends with this. The next step is to be done on the Exchange server.

 Connect to Exchange Server>Launch exchange Management Shell (Elevated).Both the below scripts should be run from elevated EMS.

a. Create a new connector:

new-SendConnector -Name 'Connector Name' `

      -Usage 'Internal' `

      -AddressSpaces 'SMTP:AliasDomainName;1' `

      -IsScopedConnector $false`

      -DNSRoutingEnabled $false `

      -SmartHosts 'SharePoint web server name (where SMTP server is installed)'`

      -SmartHostAuthMechanism 'None' `

      -UseExternalDNSServersEnabled $false `

      -SourceTransportServers 'Exchange Server Name'

b. Create an accepted domain in Exchange Server

New-AcceptedDomain -Name ' Alias Domain Name ' `

      -DomainName ' AliasDomainName ' `

      -DomainType InternalRelay

24) Now try sending the emails to your document library email address. If the mails are not being received in the document library, make sure that the SMTP server is running on the server. (Open IIS 6.0 Manager. Click on the server name on the left pane -> SMTP Virtual Server -> Start)

25) If you face issues where the email gets stuck in the drop folder, refer this post.
