    NAME
    add_recip, madd_recip - add recipients to recipient list

    SYNOPSIS
    int add_recip(reciplist *plist, char *name, int checkdups)
    int madd_recip(reciplist *plist, char *name, int checkdups)

    DESCRIPTION
    add_recip() adds the name to the recipient linked list.
    If checkdups is set, it first checks to make certain that
    the name is not in the list.

    madd_recips() is given a list of names separated by white
    space. Each name is split off and passed to add_recips.
