OT: Mail archives

Lawyer asked me to dig up some email correspondence from
~20 years back.  Of course, any MUA under windows -- in
that era -- likely stored mail in a proprietary format.
In my case, OE used dbx files which are tedious, at best,
to parse with a hex editor.  :<
<http://www.mitec.cz/mailview.html> seems to do the trick
(though the UI is a bit cumbersome).
I'll have to poke around their site to see if there are other
useful "goodies"...
