[Evolution] Export and imports mails

[Shams Fantar <sfantar snurf info>]

Hi !

I would like to change my mail client because currently, I'm using 
Thunderbird and so, I hope to use Evolution. :-)

But there is a problem, I cannot import my mails from Thunderbird to 
Evolution.

Look this picture[1].

The field "file type" is gray...why ? Ideas ? It's similar with "Inbox".

Regards,
