[TenTec] ADMIN: Message "The message's content type was not explicitly allowed"

[Jim Lowman]

This is not a knock on your literary content, guys.

This error is typically caused by sending messages to the list in other 
than plain text.  It has nothing to do with the content of your message.
Ensure that your e-mail client is set to send plain text, and not HTML.

Many mailing lists are configured to reject messages sent with HTML, as 
they can contain some nasty surprises.

Some of the e-mail clients that I've used are configured to send in HTML 
or rich text by default.  This was a problem with AOL users for quite a 
while.
