Believe it or not, I received an out of office to the post I'm
replying to :)  So as I indicated, I wrote an autoresponder to deal
with this crap.  But first, I must apologize in advance, in case this
thing backfires in an infinate loop and replies to the list.  Here is
the latest script:

  PRC_LIBRARY_DIR=$HOME/procmail
  
  SENDER_ML=(owner-(\
  amanda-users@amanda\.org\
  |cryptography@metzdowd\.com\
  |cypherpunks@[a-z0-9.-]*(lne|ssz).com\
  |mixminion-dev@freehaven\.net))
  
  # Sender is owner mailing lists
  #
  :0 
  *$ ^Sender:.*$SENDER_ML
  * ^Sender:.*owner-\/[a-z0-9.-]+@
  * MATCH ?? ()\/[^@]+
  {
    LISTNAME=$MATCH
  
    LOG="+_+_+_+[ Anti-OOO ]+_+_+_+$EOL"
    INCLUDERC=$PRC_LIBRARY_DIR/ooo_responder.prc
  
    :0 E:
    mailing_lists/${LISTNAME}
  }
