Export and migration

Hello there !

I'm disappointed because I don't know how to export Kmail-Data from scratch.
There's no option in menu and I think that is a lack, because some people
might migrate their data to another installation on another computer.

Import does rarely work, but makes me worrying about integrity and 
efficiency ...

Please implement a solution to export mail-data in an (f.e. csv-File) archive
that can be importet either by furter versions...

I wasn't able to export my mail-data completely to my new installation.

With best regards,

Torsten Gralke.
