set Content-Type in CLI?

[Bryan Bibb <bryan@xxxxxxxxx>]

Is it possible to have Mutt set the Content-Type from the command
line?  I have a colleague who would like to send an HTML message within
a script.  

For example, you can do this and it works:

---
bryan@whirlwind:~/linux$ echo "From: me@xxxxxxxxx
Subject: something
To: me@xxxxxxxxx
Content-Type: text/html; charset=iso-8859-1

testing" | /usr/sbin/sendmail -t
---


But, if you try this, it doesn't (the message just comes as plain text):

---
bryan@whirlwind:~/linux$ echo "From: me@xxxxxxxxx
Subject: something
To: me@xxxxxxxxx
Content-Type: text/html; charset=iso-8859-1

testing" | mutt -H /dev/stdin
---

I have successfully used the -a switch to attach an html file, which
creates a multipart/mixed message with an html part.  But this isn't
quite on target.

I have a notion that I could use the -e switch to send a configuration
command (a send_hook?) but I haven't found any documentation on the
syntax of this switch.

Any help would be greatly appreciated.
