There is a pretty simple way using Eudora 'Automation'
If you create a nam.MSG file with
-------------------
To: contact@school.edu
Subject: Transportation list for mm/d/yy
From: you
(blank line)
body...
------------------------
and start Eudora (any Eudora client even the Lites, after 3.0) with the command line
..\eudora.exe nam.msg
It shoves the output into the outbox.

nam.msg is [d:][\path\]filename.ext and
contact@school.edu is the email address of person to receive, or list of email addresses.

Look for Eudora Automation on the Qualcom site.
A simple batch file could arrange this, e.g export the text to a folder, prepend the appropriate header, even a COPY command could to that, then send the files into eudora.
Or as you are already using a variety of languages, not very many VB or Delphi lines could extract the message, put the header on and spawn the eudora add, one per message to send.
It takes Eudora about a second to absorb each message, so for less that two hundred count on three minutes, and similarly for Eudora to send, depending on connect speed, cpu......
Working in ASCII is so easy to debug it should not be an arduous task. The first test can be done with NotePad as a compiler
