I'm a bit perplexed about all the talk of parsing UNIX mail files. If
you're storing files in UNIX mail format, that implys that you're
getting your mail via UNIX sendmail. That means you're running a UNIX
system, so you might as well read your mail using a UNIX program.

But why do you want to read such files? No self-respecting LispOS
would store mail in UNIX mail format.
