We have just purchased a Barracuda Spam Firewall 300, we have set it up but are having problems authenticating with our Exchange server (2007). I spoke to Barracuda about it and they said I need to exclude the Barracuda box from authentication from within Exchange, how do I do that?

  • 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!

I believe this is what you are looking for:


  • 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?

  • "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." shudnow.net/2008/02/10/…
