let me get this straight. when somebody who is on the list, is also in the CC:
of the message, it wont get the mail from the list, only from the original
poster, right? that's what this DontReceiveDupes does.
but the other members of the list do get the mail. they should see in the Cc:
that one person, who didn't get it because of above condition. or am i wrong here?
