Default Detect / Filter BB Traffic?

Please Login to Remove!


I work in an IT department that would like to find out how many of our users are connecting to our email system via IMAP over BIS. So far, all we've come up with is detection via IP Address. But for that to work, we'd need to know all of the IP Addresses used as proxy servers by the various carriers.

Here are some questions:
1) Am I on the right track? Asking the right question? Is there a better way to detect BB usage?
2) Do I understand the architecture correctly? Am I looking for BIS proxy servers?
3) Does such a list exist? Even a partial list would be helpful.

EDIT: 20090304_1516
After a little more research, I see that I'm partially wrong. The devices are not accessing our IMAP server directly. The BIS servers are accessing our IMAP server and relaying the mail to the devices. So, what I really need is the pool of addresses used by RIM's BIS servers. Does that sound right?

Huh, after a little MORE research I found this "Firewall and connection requirements for the BlackBerry Internet Service", which I believe answers my question. So, sorry for any trouble - I should be good now. [I can't post the link, my post count isn't high enough.]
