I'm in the same situation right now (moving to a new PC) and I'm a little confused. I looked in this directory:
/home/tyler.mozilla-thunderbird/default/{HASHKEY}.slt/Mail/
And I saw a folder for each of my accounts in there. But is this ok? I'm pretty sure that one directory is a hash key and I'm just concerned about having that directory name be something different when I install Thunderbird on my new system...
