Which version of exchange you are using?
Seems to be a permission issue on the exhange SMTP.

You'll want to check that this is the same for Exchange 2010 - but this is how to fix it in 2007...

First, create a new receive connector for the relay.  Let's assume you name it 'External_Relay'.  You're going to change the security permissions so it is best to use a specific, segregated connector.  Make sure that you allow the 'Anonymous Users' Permission Group.

For security, allow the relay only from the host that needs to send the emails.

Now you need to do the crucial bit....

Add the adPermission to the connector:

Get-ReceiveConnector -Identity 'ServerName\External_Relay' |Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

I'm fairly sure this will be the same in 2010.

Godd luck!
