[net.mail] local mail functions

lmc@denelcor.UUCP (Lyle McElhaney) (02/07/84)

Has anyone out there tackled a scheme for providing internal and external
mail handling?  What I have in mind is the following situation:

   external usenet world
	   \ | /
	    \|/
	   mail
	  handler
	 /   |   \
	/    |    \
       A-----B-----C  ......
	\_________/

All the internal machines (the handler, A, B, and C) can intercommunicate
in a normal manner, by addressing the target machine explicitly.  Normally,
however, mail is simply addressed via the mail handler, who holds it till
requested by the addressee on any of the machines.  It is then routed to
that machine.  Mail going externally is sent to the mail handler, who
prunes out any internal information in the headers and sends the stuff out.
External incoming mail is treated like internal mail (held and forwarded on
request).

The internal machines are a combination of types, running UNIX of various
kinds (mostly System 3 and 4.2), so the solution needs to be applicable
to all.

Thanks for any help supplied.

We are doing something like this with "MLNET", using one machine
"uwo" as a gateway between uucp generally and both a local mail
forwarding network (in operation) and a wide-area mail forwarding
operation similar to EDUCOM's MAILNET system.
