Raymond,

It _should_ be fine to pop the HDD into 
another box and let it discover the new 
hardware, but never rely on it.

Make a backup of "/etc" and "/var", and 
store them someplace safe. There may 
be other places that configuration info is 
stored, but that is at least a good start.
Maybe store the output of "rpm -qa" in 
a safe place, along with any rpms/packages
you downloaded separately from the original
red hat distribution.

That way, if the "hardware discovery" 
option goes bad, turn it into a fresh install 
and pull your backups/extras onto the new 
host and selectively replace the files you 
updated originally.

Hopefully someone can give specific information 
on sendmail install files, but you should be able 
to get most of that info from the man pages, 
Email HOWTO, and from using "rpm" to 
query the sendmail package.

Good luck,

Troy

Last week I had a mail server crash, so I set up a new Redhat 7.3
server
for mail and web. I have manually added the users, and was pretty happy
to
resolve the problem. it now looks like the PC I used is unstable, so I
have
to move everything to another box. Can I just pop the HD into another
box,
and let it find new hardware? if not, I could use some info on what
files
to backup and restore to the new box, so I am able to preserve users,
passwords, and mail.

Thanks in advance
