  33     NAME
  34         add_recip, madd_recip - add recipients to recipient list
  35
  36     SYNOPSIS
  37         int add_recip(reciplist *plist, char *name, int checkdups)
  38         void madd_recip(reciplist *plist, char *name, int checkdups)
  39
  40     DESCRIPTION
  41         add_recip() adds the name to the recipient linked list.
  42         If checkdups is set, it first checks to make certain that
  43         the name is not in the list.
  44
  45         madd_recips() is given a list of names separated by white
  46         space. Each name is split off and passed to add_recips.
