I have sendmail-8.13.7 and dovecot-1.0-0.beta8.2 and on FC5. To prepare
for the event that my machine crashes some day, I would like to know
what are the files that I should backup and how I should restore those
backup files on a new machine.

I am using dovecot for IMAPS.

I can think of the following files:
/etc/mail/sendmail.mc
/etc/dovecot.conf
/etc/aliases
/var/spool/mail/* --> emails of all users
/home/*/mail/.imap/* --> IMAP settings/emails of all users
/etc/passwd --> If I migrate this file, will I still need to create all
the users again?
/etc/pki/tls/certs/sendmail.pem

Is the above list correct?
Would I need to perform any other step?

/etc/shadow
/etc/group

Better yet take the whole /etc

Home directories may need to be recreated.
