[Peter Eijlander (PA0PJE)]

Don (and Jim for info),

There could have been another reason for not showing any text in the 
text-part if the message.

Jim might use a device like a "smart"phone  that sends HTML-only mail.
This mailman server is set to suppress and delete any HTML markup and 
attachments in received mails before sending it to all participants.

So, for anyone reading this: Send at least Plain Text + HTML or better 
still Plain Text Only to this mail-reflector.
