[Evolution] Mail from shell command line

[steven Lobbezoo <steven revimmo com>]

Hi,

I would like to construct an e-mail message in an other program,
then open a "newmail" window in evolution to allow the user
to edit the message, and then send it.
The message is composed of HTML and several images.

I could not find how to do this. I tested a bit, and can setup a message,
give it a receipient and a header, but not the body.

Anyone can help me with this ?
Steven
