They don't. You'd need a proper cpanel archive to get those (there's a file that's created during a full backup specifically for the mail settings), which can't be created with the server inoperative. The mail itself is in your home folder though, so you do get your mailbox content back Because these backups were made with the server offline, we just tarred the home folder and copied the files for your databases. Postgres, mail settings, domain configurations, etc. were not backed up.
