Now you've caught my attention; first of all, there are more than 3M
messages stored in the lkml.org datase, so I guess you've missed some
messages or something is really broken.

Besides, unless you figured out how to get to the raw data, you've just
scraped a rendering which discards stuff like pgp signatures etc and has
very incomplete headers. Unless you don't care for those of course :)

Note that I've also been toying with the lore dataset, and wrote a tiny tool
to get Maildir-like data out of it; this code is a bit of a single-use-jig
so you'll need to do some coding if you really want to use it.  Attached
anyway.

All the best and enjoy,
Jasper
