[comp.mail.sendmail] External domains

rbraun@spdcc.COM (Rich Braun) (05/16/91)

OK, I admit it.  I'm another sendmail victim, a person who just can't seem
to figure out sendmail.cf files.  And "ease2" isn't necessarily a
panacea for me; I downloaded it but am daunted by the task of figuring
out yet another seemingly complex subsystem.

I have bidirectional communications capability that works at least
somewhat between an RS/6000 and two other offsite systems running UUCP.
One of them is on the Internet, and the other one goes through a couple
of UUCP hops to get there.  Complicating things are:  (a) I've got some
local systems that insist on using MMDF in conjunction with sendmail
(thanks, SCO!), (b) one of the two UUCP links seems to munge the
"from" address on e-mail, due apparently to a coincidence in the name
of my company and the name of another UUCP-connected system down the
line, and (c) my company says I have zero dollars to spend on this.

I've got it somewhat working through the Internet system (from which I'm
doing this posting):

	- Outbound mail looks like
		From: kronos!richb@ursa-major.spdcc.com
	- Inbound mail looks like
		From: user@host.domain

If I reply to inbound mail like that, it goes into a "deferred" status
in my mail queue because sendmail can't figure out where host.domain is.
I want it to parse the domain and send anything that isn't to "anyhost.
kronos.com" via the UUCP link.

On systems other than my UUCP-linked system, I want them to route the
mail through that system for external domains.

And I want my UUCP-linked system to tell remote mailers that its name
is "kronos", the company name, and I want it to tell local SMTP mailers
that its name is "somethingelse.kronos.com".  Right now it lies and
says its name is "kronos.kronos.com".

Any helpful hints on how to combat sendmail misery?  I took a quick look
at smail and concluded that it's probably not necessary for my situation.

The domain name server might also need to be configured locally.  Once
I figure this thing out, I'd like to register our site on the Internet;
I believe MX records are intended only for systems on the Internet which
want to know the relay for an off-the-net system like mine.  (If you
have a Boston-local system on the Internet which could serve as
a UUCP relay for my site, I'd like to talk more about it.  Uunet is
clearly overkill.)

Finally, is MMDF capable of talking directly to sendmail via SMTP?  The
SCO documentation skirts this issue, though it is quite clear that MMDF's
host tables require explicit names for every conceivable system to which
I'd want to talk.  (It doesn't use the domain name service.)
