Moving from Mail 2.0 to Thunderbird
Apple Matters has produced a walk-through
on switching from Mail.app to Thunderbird using the emlx to mbox converter from CosmicSoft.
It covers all the steps from finding your Mail.app messages, converting, moving and importing them again and features some screenshots to help you on your way.
Perhaps the emlx to mbox converter has got smarter or perhaps the author was lucky, but he doesn’t mention any of the problems encountered by another user trying to do the same thing, which were posted on macOSXHints
some time ago.
Needless to say, moving back the other way again from Thunderbird to Mail 2.0 will be easier and the outcome more pleasurable.

I’m not clear why anyone should use a conversion program at all.
Open Mail > Highlight all the messages in the relevant folder > File > Save As
and alter the dropdown menu to read “Format: Raw Message Source”.

I should add that Mark Pilgrim’s complaint about Mail’s “broken” export feature to mbox–which I just detailed above–was that it didn’t add a control character before any sentence beginning “From”. However, I don’t know of any other mail client that does add a control character *on export*.
Mail adds one *on composition* of an email, and–as with Thunderbird–it uses a space (not a greater-than sign). Is this perhaps linked with both clients’ use of the modern format=flowed standard?
Incidentally, format=flowed is a standard that the Evolution mailer that comes with Ubuntu has still not implemented. I mean, come on guys, we’re living in an era where the output device could be just about anything (from a widescreen to a smartphone) so text should be wrapped to *whatever* size of screen/window is used/chosen not artifically broken in lines suitable for a 70s console and with greater-than signs arbitrarily intruded. :-)
