rsalz@bbn.com (Rich Salz) (11/15/89)
Some people might find the following config files useful. They're
primarily for a site on the Internet that acts as the mail server to a
group of other workstations and servers. All mail goes through the major
relay. No UUCP connections, although that should be pretty easy to add.
(Run smail.) This runs on a stock sendmail5.61 with bind picked up from
Berkeley.
As you might have guessed from my previous posts here, I've gone to some
trouble to strip out useless stuff (e.g., "HSubject"). I also removed
support for some old syntax, added comments, and reformatted and
restructed the whole file. I think they're lots easier to read now. The
final thing of note is that there are two TCP mailers defined, and two
types of host hiding: mail sent outside of BBN goes out with
"rsalz@bbn.com" but internal mail sees "rsalz@MYHOST.bbn.com"
Since I'm a firm believe in the domain system, the only fake domains are
uucp and bitnet. If you use these files, change the uucp mailer!
Hope others find these useful.
