moving Netscape mail folders

[Jamie LaRue]

I did manage to import my old Mac-based Netscape address book into
Mozilla, then export it again to be read into Evolution. But I'd kind of
like to import all the old mail folders, too.

Don't see a way to export them, however. On the Mac, it's in
/System/Preferences/Netscape Users/My name/Mail.

But if Mozilla uses the same kind of directory structure, I can't find
it. And when I tried to read just one of the folder files in (either
plain or with the .snm extension) it didn't work. Anybody else?
