+/* DESCRIPTION
+/*	This module maintains lists of recipient structures. Each
+/*	recipient is characterized by a destination address and
+/*	by the queue file offset of its delivery status record.
+/*	The per-recipient status is initialized to zero, and exists
+/*	solely for the convenience of the application. It is not used
+/*	by the recipient_list module itself.
+/*
+/*	recipient_list_init() creates an empty recipient structure list.
+/*	The list argument is initialized such that it can be given to
+/*	recipient_list_add() and to recipient_list_free(). The variant
+/*	argument specifies how list elements should be initialized;
+/*	specify RCPT_LIST_INIT_STATUS to zero the status field, and
+/*	RCPT_LIST_INIT_QUEUE to zero the queue field.
+/*
+/*	recipient_list_add() adds a recipient to the specified list.
+/*	Recipient address information is copied with mystrdup().
+/*
+/*	recipient_list_swap() swaps the recipients between
+/*	the given two recipient lists.
+/*
+/*	recipient_list_free() releases memory for the specified list
+/*	of recipient structures.
+/*
+/*	RECIPIENT_ASSIGN() assigns the fields of a recipient structure
+/*	without making copies of its arguments.
+/*
+/*	Arguments:
+/* .IP list
+/*	Recipient list initialized by recipient_list_init().
+/* .IP offset
+/*	Queue file offset of a recipient delivery status record.
+/* .IP dsn_orcpt
+/*	DSN original recipient.
+/* .IP notify
+/*	DSN notify flags.
+/* .IP recipient
+/*	Recipient destination address.
+/* SEE ALSO
+/*	recipient_list(3h) data structure
+/* DIAGNOSTICS
+/*	Fatal errors: memory allocation.
