Patrick is correct as to what happens, but it is a mystery to me why this is done. The AvoidDups handler makes a list of all explicit recipients of a message (addresses in To:, Cc:, Resent-To: and Resent-Cc:). It then goes through the message recipients (normally, the non-digest list members with delivery enabled) and any message recipient that is a list member and has DontReceiveDuplicates set is removed from the message recipients so that address doesn't receive a list message because it presumably receive a directly addressed message. So far, so good. But then, for reasons I don't understand, AvoidDups then removes this address from the Cc: header, if that's where it was. It doesn't remove it if it is in To:, Resent-To: or Resent-Cc:. It just removes it from Cc:. It is not clear (to me at least) why. But the bottom line is any address in Cc: that would otherwise have received the post from the list and that has DontReceiveDuplicates set will not receive the post from the list (because it presumably received the Cc:) and will be removed from the Cc: header of the message sent from the list. Note that this does not affect digest members who are in Cc: because they will not be candidate recipients of the message. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
