	Indeed, ANYBODY can send LWSP with TABs in it (per RFC-822).
	Somehow just most don't do that..

	I didn't know that ZMailer touches on Subject: at all, nor
	should it touch on Date: it receives from somewhere.
	OTOH From: and To: it does rewrite.

	Configure with option:
		--without-rfc822-tabs

	One finnish company creating groupware software had same mis-
	interpretation of what "whitespace" means, and their software
	blew up with TABs...  We would not have cared of it if it had
	been one or two sites, but it was a few tens of customer sites..
