If you search the net, you will find this procmail receipt:

# no duplicate Message IDs, please
:0 Whc: .msgid.lock
| formail -D 8192 $HOME/.procmail/msgid.cache
  :0 a:
  duplicate


FWIW: It's basically the same, as I keep talking about to deleted
duplicate mails based on the Message-Id header.

Please note, that this script doesn't perfectly fit /this/ particular
issue. Almost all direct copies reach the recipient before the list copy
does. Which means, the list copy will be dropped (as the Message-Id is
known) and the private copy will end up in the mail tree. But this copy
does not have the List-Id header -- which effectively breaks proper
mailing list filtering...

A workaround to accomplish what you really want should be: Drop all
mails with known (aka subscribed) mailing list To/Cc headers and without
any List-Id header. This will drop the personal copy, and the list post
can be filtered based on proper List-Id header.

Please bear the poor developers, hackers and volunteers in mind, trying
to help folks...
