	Yes, much of it is woven into the code.

	Very much of things are in forms of "property lists",
	that is:   ( ... "name" ("value") ... ) -pairs, and
	there can not be just two "name"s after each other,
	thus:  'external external', and (spurious) 'env-end
	env-end')

	'external' says that the message came in thru some
	external channel, and that the owner of the spool-
	file is not to be trusted -- owner is "daemon", and
	it is unacceptable in this case for direct storing
	into an explicitely defined file:

	MAIL FROM:<...>
	RCPT TO:<"/etc/hosts.equiv"@....>

	.. just as an example.
