+/*++
+/* NAME
+/*	smtp_misc 3
+/* SUMMARY
+/*	SMTP client address rewriting
+/* SYNOPSIS
+/*	#include <smtp_addr.h>
+/*
+/*	void	smtp_rewrite_generic_internal(
+/*	VSTRING *dst,
+/*	const char *src);
+/*
+/*	void	smtp_quote_822_address_flags(
+/*	VSTRING *dst,
+/*	const char *src,
+/*	int flags);
+/*
+/*	void	smtp_quote_821_address(
+/*	VSTRING *dst,
+/*	const char *src);
+/* DESCRIPTION
+/*	smtp_rewrite_generic_internal() rewrites a non-empty address
+/*	if generic mapping is enabled, otherwise copies it literally.
+/*
+/*	smtp_quote_822_address_flags() is a wrapper around
+/*	quote_822_local_flags(), except for the empty address which
+/*	is copied literally.
+/*
+/*	smtp_quote_821_address() is a wrapper around quote_821_local(),
+/*	except for the empty address or with "smtp_quote_rfc821_envelope
+/*	= no"; in those cases the address is copied literally.
+/* DIAGNOSTICS
+/*	Fatal: out of memory.
+/* LICENSE
+/* .ad
