Subject: _dispose(): Inhibit replybot when Precedence: is any of bulk, junk,
 or list.  Chuq gives us the relevant info from the sendmail docs:

      When  the  name is found in a "Precedence:" field, the
      message class is set  to  num.   Higher  numbers  mean
      higher  precedence.   Numbers  less than zero have the
      special property that if an error occurs  during  pro-
      cessing  the body of the message will not be returned;
      this is expected to be used for "bulk"  mail  such  as
      through  mailing  lists.   The  default  precedence is
      zero.  For example, our list of precedences is:

          Pfirst-class=0
          Pspecial-delivery=100
          Plist=-30
          Pbulk=-60
          Pjunk=-100

      People writing mailing list exploders  are  encouraged
      to use "Precedence: list".  Older versions of sendmail
      (which discarded all error returns for negative prece-
      dences)  didn't  recognize  this  name,  giving  it  a
      default precedence of zero.  This  allows  list  main-
      tainers  to see error returns on both old and new ver-
      sions of sendmail.
