Enabling anonymous relay for a receive connector in Exchange 2013
JaredBusch last edited by
I recently upgraded a client that was running Exchange 2007 to Exchange 2013 and ran into a problem with their "anonymous" receive connector no longer relaying email.
The answer was a single powershell as follows.
Get-ReceiveConnector "Anonymous Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"
This was listed on a Technet article related to Exchange 2010.
