Hello all, I was hoping someone might be able to give me some useful insight on an issue I've been having. What I want to do is enable my Exchange 2007 server (hub, mailbox, CAS) to be able to forward anonymous SMTP from specific IP addresses. I've created a new send connector titled anonymous relay. I added the specific subnets in the remote subnets tabs and also ran the required shell commmand: Get-ReceiveConnector "Receive Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient" This seemed like a pretty straight forward task but it doesn't seem to be working and I've followed microsoft documentation. Has anyone else ran into this issue? Any help would be greatly appreciate, thanks in advance!

Did you restart the Transport Service after making the changes? Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Yes I did, but still no luck...I can't imagine what's wrong it seems pretty simple.

I presume you are following these instructions? http://blogs.technet.com/b/exchange/archive/2006/12/28/3397620.aspx I would delete the connector completely and set it up again. I have seen third party tools, such as AV (McAfee for example) block this kind of traffic as well. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Have you enabled and checked the SMTP logs for these two receive connectors? Set the logging to be verbose and then check the logs on disk. http://technet.microsoft.com/en-us/library/bb124531.aspx How are you testing? Test via telnet and see where it is failing http://support.microsoft.com/kb/153119 I have a suspicion that it is hitting the default receive connector rather than your new one. Also curious as initially you say you created a send connector, and then in the code sample it says receive connector, can you confirm it was a new receive connector that you made??Cheers, Rhoderick
