I have a somewhat dumb question about mail delivery. This has a CP connection because it relates to a remailer enhancement I am working on. When I receive mail from cypherpunks, this is a typical set of headers for an incoming message: From owner-cypherpunks@toad.com Wed Oct 20 23:57:11 1993 Received: from nova.unix.portal.com by jobe.shell.portal.com (4.1/1.34) id AA14713; Wed, 20 Oct 93 23:57:11 PDT Received: by nova.unix.portal.com (5.65b/4.1 1.505) id AA18779; Wed, 20 Oct 93 23:57:09 -0700 Received: by toad.com id AA20355; Wed, 20 Oct 93 23:47:55 PDT Received: by toad.com id AA20115; Wed, 20 Oct 93 23:43:21 PDT Return-Path: <jamie@netcom.com> Received: from netcom.netcom.com ([192.100.81.100]) by toad.com id AA20111; Wed, 20 Oct 93 23:43:19 PDT Received: from netcom3.netcom.com by netcom.netcom.com (5.65/SMI-4.1/Netcom) id AA27104; Wed, 20 Oct 93 23:43:51 -0700 Date: Wed, 20 Oct 93 23:43:51 -0700 Message-Id: <9310210643.AA27104@netcom.netcom.com> X-Mailer: Eudora To: cypherpunks@toad.com From: jamie@netcom.com (Jamie Dinkelacker) Subject: Re: Something Silly, Something Serious Status: RO Now, my question is, when this mail is delivered to the Unix system which I use, how does the local software know to deliver it to hfinney? My name does not seem to appear in the header at all. In particular, the "To:" address is not hfinney@shell.portal.com, as I would have expected, but rather cypherpunks@toad.com. I suppose there is some other information that is passed along with the message when it is delivered to portal.com, information which tells my user name. It would be nice if this information were available to scripts which would process the incoming mail. Could someone explain how this delivery process works? Thanks - Hal Finney hfinney@shell.portal.com
