Exchange 2010 internal relay

Hi guys,

I have set up an exchange 2010 server onto a server 2008 box, i have been having difficulties in getting relay to happen, I can telnet to the server from the addresses i have defined in my connector but cannot relay mail to it, I have a single server environment, any help would be greatly appreciated

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This gets nasty on 2007/2010. Have a read of this and weep... It seems that Powershell will be a necessary skill for Exchange admins from now on as some things cannot be set in the GUI any more.

This is the relevant line:
"This grants the most common permissions to the anonymous account, but it does not grant the relay permission. This step must be done through the Exchange shell:

Get-ReceiveConnector "CRM Application" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient""

Are you talking about receiving mail or allowing another server to relay to the exchange server?

I am guessing because you say single server envronment that you are talking about being able to receive mail?

In which case Exchange 2010 by default books anony ou's relay which of course unless you want to tell everyone that sends you email what credentials to use (which is pretty impossible) you will have to set the receive connector to allow anonymous user access.

In the Exchange Management Console navigate to Serer Configuration > Hub Transport right click on the receive connector called Default SERVERNAME and select properties.  Then in the last tab (permission groups) check te box for anonymous users.  Once done restart the Microsoft Exchange Transport service.
