I've just installed Debian 9 (stretch) and I'm trying to import folder
with messages from Icedove 38.5.0 at my
old PC (running debian 8) to my new PC with Thunderbird
In Icedove I select a folder and Tools -> Import/export in
mbox/eml format -> Export folder
And save the file in a pendrive.
Thunderbird I select Tools -> Import -> Messages ->
Mail -> Next
But appear only the message: No application or data file to import
option to select the file that contains the
contact list as in
Please, any tip?
