This feature request is to put in a wizard based functionality to backup and restore accounts configured in KMail across desktops. A typical UseCase would be that I setup and configure an account on Desktop A (for a specific OS, say Fedora 7). Then, through a wizard, I backup all data ie account metadata, account configuration data and mailboxes associated with an account to a package payload - perhaps an archive. On Desktop B, for any OS where KMail is available, I use an wizard to import the package payload from Desktop A and thus end up with the exact same mail account along with the account metadata, account configuration data and mailboxes.

Note, this is not "importing" mailboxes of a different MUA on the same machine which is an UseCase for MUA migration from something_else to KMail. This is a backup/restore across desktops.
