Saving user accounts on reinstall

I am looking to reinstall an email server. I want to keep my user accounts
and passwords and transfer them to the new server. Is it as easy as copying
/etc/passwd and /etc/shadow and the /var/spool/mail directory?

And the home dirs, aliases and "mta".config too :)
I had no problems doing so in that way.

Depends on your MTA :)

For sendmail its usually /etc/mail/*

Beware that you may need to rebuild the sendmail.cf if you're updating from
and old version to a newer one.

Having just done this I'd include /etc/group and /etc/gshadow and don't
forget to trim the system accounts from the old files before adding to the
new ones.

And, if any of your "old" users have an exotic shell, don't forget to
twiddle /etc/shells.

I do not include any system account info (typically uid less than 100 )
from passwd, shadow, group, and gshadow. I then concantenate that info
into the respective files on the new server.
