Looking at Exchange I already created a Receive Coonector for the Spam Filter with the IP/Sub Net for that box, with Anonymous User permissions with TLS security. I think I just need to run the command, I'll try that, thanks! – stead1984 Jun 16 '09 at 9:44

What does the following command actually do? Get-ReceiveConnector "Receive Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient" Any idea's? – stead1984 Jun 16 '09 at 9:59
"The above command gives the Anonymous Logon account permission to Ms-Exch-SMTP-Accept-Any-Recipient (relaying) on the specified connector. That way, once you have allowed anonymous users to use that connector as well as grant them Ms-Exch-SMTP-Accept-Any-Recipient, they will now be able to relay via the specified connector."… – Joseph Jun 16 '09 at 13:56
