It would have been easier if you'd mentioned your email software.
Since you are using OE6 you can export the message as a single ".eml"
message. While the OE 6 format in the "OutlookExpress" directory is
unreadable by mortals the ".eml" format is standard mbox format. That
can be fed directly into the unlearn process modulo a possible need to
excise carriage return characters, an exercise left to the student.
