Now that I have been on site and got a good look at this I can give out some more info. First the systems is something new Qwest is offering to customers. They install a small client on their Email server this gets past the password and forwards all email back to a qwest storage client waiting for the Cell phone to register. This is where the problem comes in, any phone on the system that knows the server/domain can register and re-register with different clients names and gets their email to the phone. The Authentication is just that you know the server/domain name and select a username. Giving access to any one in the company's email. My customer turned the phones back in after we found out how it worked.

Not new, special accounts for the phones themselves? Your email really doesn't give up too much information... ----- Original Message ----- From: "David B.

The problem is that the customer never gave out the passwords and the server is behind a firewall not controlled by Qwest so how do the phones have access to the server for email without ever asking for a password during setup or at time of request?

So yes, anyone with a cloned cell can get the email. =================== Stephen A Santos 63 W Fountainhead Dr #107 Westmont, IL 60559 H: 630-241-0493 M: 630-561-9368 -----Original Message----- From: David B.

A customer of mine is testing a new cell phone from Qwest. It gives them access to cheap cell phone connection and Internet mail. The problem is it connects to exchange without a password. I can see if qwest was the server location and they were doing a copy of some sort, but the server is behind a firewall from Qwest yet they are getting email to the phone both external and local. Any Ideas? Dave H
