Stop relaying Exchange 2007/2010

by Jón Ólafsson

If you like many others have Exchange 2007/2010 server and you discover that you are an Open Relay, there is a very simple command that you can run from the ems (PS) to close this down.

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

Replace “AnyReceiveConnector” with the name of your Receive Connector and then run the command.

After doing this you can visit MXToolbox or ExchangeConTesting for testing.
