>Has this ever happened to you? I'm in the process of clarifying specs, by email, with a government client. I sent a list of questions, requesting they address them. I received my answers, only to find that they CC'ed a dozen or so end-users of the application I am to be upgrading, and included my list of questions.

>Now, I'm beginning to receive messages from the end-users, providing me with their personalized wish-list, all because my client was gracious enough to provide their end-users with my email address!

You need to let your client know that the time spent responding to the people that they cc'd is just as billable as the time spent evaluating their direct responses - if they say ignore outside input, do so, otherwise track and bill your time and provide your client with a detailed breakdown of your efforts. After all, they could have circulated the memo without you in the loop and just passed things along.

>So, I sent a somewhat not-too-delicate request to my client, asking them to support my desire in keeping the lines of communication to a more official level.

Did you ream them, or simply remind them that you're billing for your efforts on their behalf based on their decision to add the end-users to the specification process.
