+/* NAME
+/*	verify 3
+/* SUMMARY
+/*	update verify database
+/* SYNOPSIS
+/*	#include <verify.h>
+/*
+/*	int	verify_append(queue_id, stats, recipient, relay, dsn,
+/*				verify_status)
+/*	const char *queue_id;
+/*	MSG_STATS *stats;
+/*	RECIPIENT *recipient;
+/*	const char *relay;
+/*	DSN	*dsn;
+/*	int	verify_status;
+/* DESCRIPTION
+/*	This module implements an impedance adaptor between the
+/*	verify_clnt interface and the interface expected by the
+/*	bounce/defer/sent modules.
+/*
+/*	verify_append() updates the address verification database
+/*	and logs the action to the mailer logfile.
+/*
+/*	Arguments:
+/* .IP queue_id
+/*	The message queue id.
+/* .IP stats
+/*	Time stamps from different message delivery stages
+/*	and session reuse count.
+/* .IP recipient
+/*	Recipient information. See recipient_list(3).
+/* .IP relay
+/*	Name of the host we're talking to.
+/* .IP dsn
+/*	Delivery status information. See dsn(3).
+/*	The action is one of "deliverable" or "undeliverable".
+/* .IP verify_status
+/*	One of the following recipient verification status codes:
+/* .RS
+/* .IP DEL_REQ_RCPT_STAT_OK
+/*	Successful delivery.
+/* .IP DEL_REQ_RCPT_STAT_DEFER
+/*	Temporary delivery error.
+/* .IP DEL_REQ_RCPT_STAT_BOUNCE
+/*	Hard delivery error.
+/* .RE
+/* DIAGNOSTICS
+/*	A non-zero result means the operation failed.
+/*
+/*	Fatal: out of memory.
+/* BUGS
+/*	Should be replaced by routines with an attribute-value based
+/*	interface instead of an interface that uses a rigid argument list.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
