[mod.protocols.tcp-ip] Black Art: sendmail.cf files

WANCHO@SIMTEL20.ARPA.UUCP (03/14/87)

It seems the root of many of the improperly formed message headers,
and the reason that many hosts have had difficulty in switching to the
domain format host names is poorly constructed sendmail.cf files.
This problem will shortly become acute when the NIC will no longer
disribute its HOSTS.TXT file containing host alias entries.

Therefore, I'd like to propose that a small handful of sendmail
wizards get together and produce one proven sendmail.cf file for each
of the major environments: Internet only, UUCP only, a combination of
the two, and whatever else they deem necessary.  Then make the
resulting versions available either somewhere on NIC or ucbvax or
both, and advertise where they are.

Of course, if this has been done already, it would pay to make that
information known much more widely, particularly at this time.

I have a sendmail.cf file that works fairly well. It has extra stuff
in it for our local chaosnet hosts, and I think it does a few things
incorrectly here and there, but it would be a good starting point for
someone who might want to tune it up a bit. It uses the domain system
and I've stripped out all the Berkeley specific cruft that most people
have. It's much less confusing than the standard distribution file.

It's in the public ftp area on hermes.ai.mit.edu.

For the combination internet/uucp sendmail.cf file, it would be good
if someone could come up with a general, automated, way of sending
mail destined for domains primarily under UUCP via UUCP, and others
via the Internet.  For those that would prefer UUCP when a site is on
both, some massaging of the first part of the pathalias output might
be in order.  I imagine, though, that most Internet sites would prefer
Internet, but would rather send mail that will eventually end up on
UUCP themselves, rather than forwarding it to seismo.  Maybe if the
UUCP Project would put out a simple list of the second level domains
that are registered with them and not on the Internet or csnet, in the
form:

ADELIE.COM
AMD.COM
ATT.COM
...
VORTEX.COM

it would be usable as a sendmail class....  (This would be especially
good for those UUCP Zone domains that don't have an Internet forwarder!)

I'd love to help, but as I'm not physically on the Internet....
