    NAME
	add_recip, madd_recip - add recipients to recipient list

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