Thanks for the suggestions Tom. Here is what I found and how I solved it.
I first checked the tape backup log file for the Arkiea tape backup software
as I suspected that this might identify if there was a problem in the hosts
file as two of our desktops are backed up from the server. This showed that
they backed up ok. I then checked the /etc/aliases file for sendmail to
verify that it had my current aliases configuration; this was ok. Then
checked the /etc/aliases.rpmnew file as you suggested. This file contained
a basic alias file that had not been custom configured. So apparently my
system updates have not over-written my configuration files. I ran the
newaliases macro to be sure that the aliases were recognized. Re-running
the newaliases command may, or may not, have been needed, but that did not
let loose mail from the queue. Finally I checked what I should have looked
at from the beginning; sendmail was not running. I am setup as a file
server and do not run a mail service, the only mail that transits our server
is the administrative messages directed to root from various applications.
I restarted sendmail and it opened the floodgates from the mail queue.
From this little exercise I have learned that my system is reading my hosts
file from /etc/hosts and not from
/etc/sysconfig/networking/profiles/default/hosts. I think I may synchronize
these files just in case something changes on my system in the future and it
looks for hosts in the /sysconfig directory.
Thanks for your assistance.
Jeff

The files in /etc/sysconfig/networking/profiles/default/ should directly
emulate what is your used configuration, otherwise upon reboot you could
lose your current settings, as I believe it loads your configs from that
directory.
I created a script awhile back that syncs up my current networking configs
to that directory, and it runs every hour, so I won't by accident lose the
settings if I have a system crash, or such a thing. Also...
Check your sendmail aliases file. More than likely, you had changed the
alias root to point to your email address, and during the up2date, it
updated sendmail and overwrote your aliases file.
If this happened, you old alias file will be /etc/aliases.rpmsave or
something to that degree.
Thanks,
Tom Callahan

Greetings -
I upgraded the kernel on my RHEL 3 file server last week and am now at
2.4.21-37.ELsmp. I was previously at the stock 2.4.21-4.ELsmp kernel.
The
results of the up2date process appeared to go well at the time. Now I
have
noticed that I am not receiving the daily email notifications for Logwatch
and my tape backup software. I looked at my /etc/host file and saw that
it
was the same as it was before updating my kernel. I checked some of my
reference manuals and one mentioned that it referenced the location of the
host file in /etc/sysconfig directory. I found a host file at
/etc/sysconfig/networking/profiles/default/host. I don't know if this
host
file was there previous to my kernel upgrade. This host file is different
than the one in /etc/host which I had previously configured for our
network.
Can anyone tell me which one I should have configured for my network? Is
it
possible that the new kernel looks for the host file under the
/etc/sysconfig directory whereas the old kernel looked for it under just
the
/etc directory?
Thanks.
