smtp-server and blind relaying...

[Matti Aarnio <mea@nic.funet.fi>]

Hello,

	Here is an extract from my development tree, where
	I have built following example while testing ideas
	for the control system.

	Do note that "relaytargets" (if defined) must contain
	also the names from "localnames" -db!

	The "relaytargets" checks at "RCPT TO:<...>" addresses,
	while "relaysources" checks at "MAIL FROM:<...>" addresses,
	and "relayhosts" checks at the IP-numbers (in ASCII form).

	Any comments/suggestions ?   (Like what to do is some
	possibly defined database is not openable ?)

	Keep in mind that my goal is to build FAST smtp-server
	without a need to run router under it...
