My last post should give you a workable solution to your problem, but I
just wanted to add an additional note about the nullclient configuration
that we discussed initially. An important point that you didn't seem to
pick up on was that the nullclient configuration actually works for me - 
it does what you want it to do. I provide the relevant output below for 
you to inspect. 

At this point of the thread you suggested that what you actually wanted 
was to have mail delivered directly to your server server02 - you said:

   "How do I make the first one connect to server02 via relay 
    instead of connecting to 127.0.0.1"

This is what led me to changing th configuration of submit.mc and heading
down that road (which also works).

The point is that these solutions actually work. If none of it is 
working for you it suggests to me that something other than sendmail 
is misconfigured on your fedora box: your DNS, your hostname, your 
/etc/nsswitch.conf, or something else like that. It really looks 
to me that sendmail is not to blame.


This is the sendmail.mc that you provided:

-- snip --
divert(-1)dnl
dnl #
dnl # This is the sendmail macro config file for m4. If you make changes to
dnl # /etc/mail/sendmail.mc, you will need to regenerate the
dnl # /etc/mail/sendmail.cf file by confirming that the sendmail-cf package
is
dnl # installed and then performing a
dnl #
dnl #     make -C /etc/mail
dnl #
include(`/usr/share/sendmail-cf/m4/cf.m4')dnl
VERSIONID(`Nullclient for Linux')dnl
OSTYPE(`linux')dnl
DOMAIN(`generic')dnl
FEATURE(`nullclient',`example.com')dnl
undefine(`ALIAS_FILE')dnl
-- snip --


When I run sendmail with this configuration, it works perfectly (read it
fully):

This is what the headers on the mail look like at the end.
