   Mailing list removal confirmation notice for mailing list cypherpunks
   We have received a request from 89.58.42.239 for the removal of your
   email address, "[3]gmkarl@gmail.com" from the
   [4]cypherpunks@lists.cpunks.org mailing list.  To confirm that you want
   to be removed from this mailing list, simply reply to this message,
   keeping the Subject: header intact.  Or visit this web page:

   [5]https://lists.cpunks.org/mailman/confirm/cypherpunks/06199da0bdf0da8
   49191d0f14e78027b97999893
   Or include the following line -- and only the following line -- in a
   message to [6]cypherpunks-request@lists.cpunks.org:
       confirm 06199da0bdf0da849191d0f14e78027b97999893
   Note that simply sending a `reply' to this message should work from
   most mail readers, since that usually leaves the Subject: line in the
   right form (additional "Re:" text in the Subject: is okay).
   If you do not wish to be removed from this list, please simply
   disregard this message.  If you think you are being maliciously
   removed from the list, or have any other questions, send them to
   [7]cypherpunks-owner@lists.cpunks.org.
