Failed to send email from outside our domain to a created distribution list email

I just tested the email address from inside our domain and it worked fine. . I tested the email using my gmail account and the test email did not work. I received this message:

Delivery has failed to these recipients or groups:
dist_orders@gatekeepersystems.com

Your message can't be delivered because delivery to this address is restricted.

What am I missing,

Thanks

This is what I got, Other email is working from our domain, it is only that one email distribution group I created in exchange. (recipient configuration-->distribution groups) This is where I created it, then added the members and then tested the email address internally. That worked. Tested externally and it did not.

smtp:216.82.254.163 smtp
220 server-7.tower-198.messagelabs.com ESMTP
OK - 216.82.254.163 resolves to mail198.messagelabs.com
OK - Reverse DNS matches SMTP Banner
0 seconds - Good on Connection time
