Thanks for the comprehensive reply. I'm still a little confused however (it is Monday morning!) There is a send connector configured on the Exchange 2010 box which must have been transferred / imported from the Exchange 2003 setup. To the uninitiated (me) it looks like a normal outgoing email connector. It has an address space of * and a cost of 1 and is routing all mail via our 3rd party spam supplier. Nothing is configured in source server and there is no mention of mail2 here. I ran wireshark and emails are definitely going out via mail2. So is this send connector being used? I will disable it to see. Are the RCGs visible in the EMC or do I need to go to the command shell. Thanks again Andy

When you introduced Exchange 2010, it created a two-way interop RGC between the Exchange 2010 server and the Exchange 2003 server you selected during installation (mail2 in your case). As far as routing is concerned, Exchange 2010 is now aware that there is an SMTP Connector with an address space of * available to it, and it has to traverse the interop RGC to reach it. As this is currently the only route out for users on Exchange 2010, Internet email is routed over the interop RGC and then through the SMTP Connector. If you now want Internet email to go out directly from Exchange 2010, you need to create a new Send connector on Exchange 2010 with an address space of *. The cost of the of the RGC and the SMTP Connector on Exchange 2003 will make the new route more attractive to those mailbox users on Exchange 2010. However, mailbox users on Exchange 2003 will likely still use the SMTP Connector due to the cost of the RGC and the Send connector but this really depends on how you've got your costs currently configured. In short, once you've confirmed that the Send connector is working correctly, you can either raise the cost of the SMTP Connector to make it less attractive or remove it completely. I typically set a new Exchange 2010 Send connector with a specific address space and test message access to this one domain first, before opening the floodgates. For example, I set the Send connector address space to silversands.co.uk then send myself a test message. I then examine the message headers and confirm the new route is working correctly before changing the Send connector address space to *.

I cannot see any reference to mail2 from the GUI. Would I have to resort to the command line to see this information or am I missing something?

The current email system is Exchange 2003. The install went fine, at some point I was asked a question regarding routing groups (I think it was this) and I chose one of the current mail servers mail2. Everything is working ok but I noticed that when I send emails they seem to go via mail2. Looking at the send connectors it seems to have imported them from the connectors on mail2 but they don't seem to mention mail2 in any of the tabs. How do I make the email go out directly from the new Exchange 2010 server?
