[Mailman-Users] no list info in cc

I have mailman set up so we can send our group newsletters. The users should never post, just receive info from us. I have it set so they are shown in the To: and my e-mail (sender) is the From:. But mailman is putting the list address in the cc . Is there anyway to alter mailman so it does not include the list address anywhere (bouces or whatever). I want it to appear like I just sent it directly to them. All is great except the cc.

Thanks, Dan
