Using multiple MX records for internal Exchange and Google Apps - turns to mails leakage to higher Delivery Precedence MX's

Hi guys,

One of our customers is working with multiple MX records as you can see in the attached screenshot.
The primary mail server is Exchange based, while the lower Delivery Precedence MX's are Google Apps based.

Even though the Exchange is fully available 24/7 with ~8.5 sec SMTP Transaction Time, some mails leak to Google Apps.

- What may be the reason for this leakage?
- Is there something wrong with our configuration?

Thanks in advance

sometimes it won't always go to the highest cost and will use any MX record
that configuration seems fine

Seth thank you.
So what would you recommend in order to provider backup for mails once the Exch server is not available?

If you are migrating to Google apps, there are apps that will allow you to back it up to local storage.  here is an example : http://www.google.com/enterprise/marketplace/%3C/viewListing?productListingId=5941+16825965296321823984&hp=topRecentInstalled
