converting old uucp buffer files to maildir

[Michael Hirmke]

Hi *,

besides my dovecot maildir structure, that has been migrated from an
Exchange server, I have an even older mail structure in an ancient uucp
style. The program named CrossPoint I used for this isn't wideley known,
but it used so called mpuffer files in a plain text format.
It is the program I still use to write for example this mail.

I wonder if there already exists a program or script to convert the
files from this program to the Dovecot maildir structure or some Howto
for writing it myself.

The format of these files looks like shown below.
Mails are separated by two new lines.
