Exchange 2010 How to send email from non-existant account

So we have a report server that sends out emails once a week/month - most of them internal but some of them external to a 3rd party that we work closely with. Since migrating fully to Exchange 2010 (from 2003) our "fake" email address of reporting_services@domain.com no longer works - or rather will only work for internal recipients. As soon as I try and send outside to the Internet it fails. I'm guessing because it wants a legit account to authorize against so as to prove its not just spam. What are my options for doing this in Exchange 2010 - in 2003 so long as the server was added to the relay list it wasn't an issue. Now it is.

I already have a receive connector created "Internal Only" with the IP of the reporting server and TLS and Basic Authentication as security mechanisms for incoming connections. Under Permission Groups I've got both Anon and Exchange Users selected. We have some other reports that authenticate fine using this same receive connector but for this particular email address there's no actual mailbox.

What are my options?

Run the following EMS command :

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

Change "RelayConnector" to the name of your new ReceiceConnector and then test - it should allow you to email externally.

That worked perfectly. Just an FYI to anyone else using the same code - if your RelayConnector has a space in it you'll need to use quotes around it (ie. "Relay Connector"). Thanks for the quick response!
