[net.mail] a mail routing service

ksh@cbosgd.UUCP (08/04/83)

The UUCP mail routing problem is coming to a head.  People are
using our Usenet map to route mail, although it was not intended
for anything more than to show news connections.  No UUCP routing
map is being kept up to date, and finding a working mail path
through the various networks is rapidly becoming quite a challenge.

I am considering offering, as a service, a UUCP routing map.  This
would be run as a business, with a charge made to customers receiving
the routing information.  Each customer would receive, on a regular
basis, a customized file containing a good, working route from their
machine to every other machine on the UUCP network.  (Here "UUCP"
means all sites reachable with the "!" syntax, no matter what the
underlying transport mechanism is.)

A sample (abridged) map might look like this:
	cbosgd		%s
	decvax		decvax!%s
	ucbvax		ucbvax!%s
	ucsfcgl		ucbvax!ucsfcgl!%s
This is the same format being used by many public domain path aliasing
programs currently in use.  The problem is that these programs do not
have up-to-date information to use to generate paths.

The UUCP mail routing map would be of the same quality as the current
Usenet map, which I put out (with assistance from my husband, Mark
Horton.)  The mail routing map would be done entirely by me.

The prices would be (tentatively) as follows:

First map:							$150
Each additional map, when requested by customer:		$100
Regular customers, a new map automatically sent each month:	$20/month

The customer would also be responsible for telephone charges to transfer
the map to their machine.  The map would probably take 5 minutes
at 1200 baud.  The customers machine could poll my machine, or
we could call you and bill you for the charges.

This message is a trial balloon to see how much interest there is
in such a service.  I would appreciate receiving comments via mail
about whether you think this is a good idea, and whether you think
your organization would be likely to subscribe to this service.

Please note that this service is for the routing of electronic mail.
It would not change the nature of Usenet (the network news), except
to make internet style addressing more widely available.  This has
nothing to do with the "Usenet Inc" that has been discussed recently.

With regard to Karen Horton's suggestion of providing a mail routing service
(for a price), it seems to me that we can use Usenet itself to distribute this
information instead.

My proposal is to create a newsgroup, such as net.mail.path, and then put a
line in crontab like:

0 4 1 * * inews -t "Paths for mysite" -n net.mail.path < /usr/lib/paths/mysite

which would post your local paths file to the net every month.  Then this
newsgroup would always have an up to date database of path data.  Obviously,
everyone would have to agree to a specific format (my vote goes for Steve
Bellovin's pathalias format, since this includes "cost" information) and there
would have to be a conversion program to remove headers (or change them into
comments).  Also, expiration times would have to be considered, and the
possibility of there being more than one article from a particular site (for
various reasons: spurious duplicate articles, overlap between new article
posting and old article expiration, etc.).  However, these problems seem to me
to be minor ones.

In addition, the current (best?) version of pathalias software could be posted
to net.sources.  Note that nmail can also use the output of pathalias.

Now don't get me wrong, I'm all for someone making a buck.  I just think
there are other problems that would be caused by cbosgd!ksh's suggestion,
(beside the cost), not the least of which is the possibility of "bootlegging"
path aliases (psst -- want to buy some paths cheap?), people trying to break
into other machines for their paths, etc.

I also think that my plan is more in keeping with the spirit of Usenet
(whatever that means) and is something that might serve to prove the worth of
the net (net worth?) for purposes other than finding out how to nuke the
slugs in your garden.

So, how about it, folks?  If this does or does not make sense, post or mail
your ideas because there obviously is a crying need for some kind of mail
routing distribution.
