|I've recently noticed that my machine doesn't leave an audit-trail
|header on mail that passes through it. (I'm sure that's not what
|it's called. I'm referring to the "Received:" by/from lines at the
|top of all mail files.)
Adding Received: headers is the job of the Mail Transfer Agent (or MTA
in mailspeak), and the quick answer is that what acts as an MTA on the
3B1 (mail/rmail) doesn't.
If you want this functionality (and other stuff, like adding other
required headers, understanding user at site.dom addresses, etc.) you'll
have to put a new MTA on the machine.
Other MTAs available include:
smail2.5 - A very small, simple MTA, does the basic stuff and nothing
fancy. Quite probably all you need if you're happy with everything
except the Received: headers now.
smail3.1 - Unrelated to the above except in name. This is intended to
be a drop in replacement for sendmail (below) but is much easy to
configure, and more flexible. It's much bigger than smail2.5.
Incidentally, it's what's I run on chance.
sendmail - The defacto standard in the BSD world, it's as easy to
operate and as painless as using manually powered dental tools on
yourself. I had to understand .cf files at one time, and I still
haven't quite recovered.
MMDF - Not a huge following, but expect that to change somewhat as SCO
is shipping MMDF as its default MTA. It has a lot going for it, but
also has some ugly bits. It's very gentle on system resources.
PP - A fairly new MTA, a descendant of MMDF by some of the MMDF
developers. Your only real option if you want X.400 compatibility.
