[comp.mail.sendmail] smail/sendmail and address-rewriting questions.

fmayhar@killer.Dallas.TX.US (Frank Mayhar) (03/29/89)

I have a couple of questions that I hope someone out there can help me with.
I'm setting up a Usenet node on a Sun 3/160 system, running SunOS 3.3.  I
want to use smail, so that we can use user@domain-type addresses in all our
mail.  So how do I reconcile the Sun-supplied sendmail.cf with the one that
comes with smail?  Basically, how do I set things up so that sendmail hands
stuff off to smail?  And vice versa?  I'm using smail 2.5.

My second question is more complicated, and it, too, is sendmail-related.
We are setting up our site to have the domain "ladc.com".  The Sun 3 system
is our sole connection to the outside world, and we want it to remain that
way.  We have a number of machines in-house, and we want to reroute mail
to the users on them, and, at the same time, hide the other machines from
the outside world (configurations change a lot).  So we want to have SMTP
and/or UUCP connections to the machines in-house, with a single (at the
moment) UUCP connection to uunet.  To do this rerouting, I want to have
sendmail rewrite the From: addresses (on outgoing mail), and the To: addresses
(on incoming mail), such that the mail reaches its intended recipient.  For
example, if I get mail to "Frank-Mayhar@ladc.com", I want it rewritten as
"Frank-Mayhar@local-machine", and forwarded.  Similarly, if I get mail to
"...!uunet!ladcgw!Frank-Mayhar" (ladcgw is the name of the Sun 3), I want it
rewritten the same way ("Frank-Mayhar@local-machine").  There will be entries
in /usr/lib/aliases that will indicate that "Frank-Mayhar@local-machine" 
is really "frank@mysun" (since most of our users get their mail on one
machine).

Is this possible to do in sendmail?  How do I go about it?  (I've read Sun's
sendmail.cf documentation, and I'm now more confused than when I started,
sigh.)  Any help, or pointers to a source of information, would be *greatly*
appreciated, by me and others.  Please reply to my Internet address, if
possible, since it goes straight to my work mailbox.  Or you can try
"known-world!uunet!ladcgw!frank", but it will probably bounce (but maybe not,
if I can get things going fast enough).

What would be *really* nice, would be the rulesets to do the address rewriting,
and an English (as opposed to what's in the Sun manual) explanation.  :-)

AdTHANKSvance!
