..or at least I assume it is and I just can't thinks straight
with this head cold.

Hi all; quick hostname question:

When mail is sent to a local user (mail -s "bla" user < file)
it's passed to the MTA as user@localhost. The same is passed
as the From address when the vacation program is run by user.

So where does the localhost expansion take place?

My problem here is that I'm getting 
	user@host.domain.name
when what I want is
	user@domain.name

I'm flying RH 7.2 and Sendmail 8.12.5 (patched) on this
particular box, by the way.

Sendmail -d0.1 -bt </dev/null gives me these responses
============ SYSTEM IDENTITY (after readcf) ============
      (short domain name) $w = host
  (canonical domain name) $j = host.domain.name
         (subdomain name) $m = domain.name
              (node name) $k = host
========================================================

which I keep reading as exactly what I want.

When I send mail from an application, be it Pine from a 
console or Netscape from a GUI, everything is as I'd hope.
My mail goes off as me@domain.name
If I send it from the command line with, say,
mail -s "blaaaa" address < file, or
senmail user <file it goes off as
me@host.domain.name

In my sendmail.cf 
host.domain.name is listed nowhere,
only, domain.name

I'm choking on this one and I know I shouldn't be. It's
like wondering why $var = 1 is not doing what it should
and 2 days of debugging hasn't helped and it only takes
a fresh pair of eyes 5 seconds to see that you really
meant $var == 1

...making me crazy.


Can anybody hold my hand?

Andrew
