That doesn't do much anyway. All it does is tell Mailman to not send to
a member whose address is in a To:, Cc:, Resent-To: or Resent-Cc:
header of the message.

Mailman isn't creating duplicates per se. Either the incoming MTA is
delivering the same message to Mailman more than once, or there is
some smtp glitch between Mailman and the outgoing MTA causing Mailman
to retry sending a message which has been accepted by the MTA, or the
problem doesn't involve Mailman at all.

Check Mailman's smtp and smtp-failure logs and the MTA logs and the
Received headers in the duplicated messages.
