I.
   A. Background
      The vacation program shipped with HP-UX in /usr/bin/vacation
      suffers from a fault in that it misunderstands it's inputs and
      invokes sendmail with the wrong parameters.  Both sendmail 5.65
      and 8.7.6 are vulnerable to this malady.  Also the vacation
      program ignores a TO: header when the "O" is upper case.
