You can do this for Mailman lists, at least when you are explicitly CC'd with an address that's subscribed to the list. You'll get the direct copy and not the list copy though. That's the best Mailman can do (anything more takes a better MUA ;).
They don't come *better* than mutt, though. At best, "different".
I know that's because I mentioned it, I didn't recall the variable name though. In the first place I don't want to see 2 copies arriving, no MUA involved here.
I suggest "/etc/init.d/$MTA stop" is the only way to guarantee that two copies of something will never arrive. The next best is to set Reply-To, which might actually have the desired effect most of the time. The next best is to set Mail-Followup-To, which won't have any effect but you will get a lot of sympathy from Dan Bernstein and Emacs/Gnus users.
P.S. You owe me $250/hr X 5 seconds / (3600 seconds/hour) = $0.35 for time & expense of fixing up the headers in this message. You pay the wire transfer and currency conversion costs.<wink>
