[Evolution] Mail import

[Clive Whelan <clive whelan btinternet com>]

Hi

I'm new to Linux (Ubuntu). I took a look at Evolution which looked good. 
However I have been a user of Mozilla Thunderbird in Win XP and despite 
extensive searching I could not find any reasonable way to transfer all 
the existing stuff from Thunderbird. It seems that I'd have to do it on 
a file-by-file basis which in view of the fact that there are literally 
hunreds of "archived" messages  in Thunderbird, is quite impractical. I 
thought at leat that I'd be able to do it on a folder basis, but 
apparently not so?
If this really is the case, I will simply have to use the Linux version 
of Thunderbird, which I can see as a newbie would also be an adventure, 
but at least seems viable.  I'd be  grateful for advice on the 
correctness- or otherwise- of my conclusions, and/or recommendations 
from someone who has done the sort of thing that I'm aiming at.
