Problems with settings for transition from Postini to Google Apps Message Security

I am currently using Exchange 2003 and Postini.  I finally got my invitation to transition to Google Apps but the invitation includes says "Your mail server is not yet configured correctly".  The link takes me to a page with instructions for configuring your firewall and mail server to allow email from Google IP's.  The problem is that I added the IP's to the Exchange server months ago. My firewall forwards port 25 using NAT to the Exchange server.

How can I test to find out if my configuration is correct?

you need to have your firewall setup for two way traffic & rulers, so you only accept SMTP from their IP range and only send SMTP traffic to their IP range.

your Postini provider should help you through this process, i decided to migrate to Mimecast, as we decided it was the better platform, and my existing provider was very good, as were the Mimecast migration team, as they were handling a lot of companies switching.

since you would normally have paid support from Postini/your provider, they should be assisting you in this process, but you might want to also look at moving to Exch2010, as 2003 is no longer supported at all from next month.

I ended up calling Google support.  It turns out that the configuration was correct on my end and there was no action for me to take.

The answer to my question was to contact Google Apps support.  Since my configuration was correct, there was no other way to get the answer that I needed.
