Exchange 2010 Allow relay to outside

One of my customer wants to send their application notification via their MS Exchange 2010 server.Then we have created receive connector in exchange, and it worked with internal email addresses.But it doesn’t send eamils to outside.

Finally we found and have to give the permission to anonymous group to relay emails to outside.


1. Create a receive connector

2. Allow anonymous login to relay the email using below power shell command(my receive connectors name is “notification”)

Get-ReceiveConnector “Notification” | Add-ADPermission -User “NT AUTHORITY\ANONYMOUS LOGON” -ExtendedRights “ms-Exch-SMTP-Accept-Any-Recipient”
