The previous one was done by this:

----------------------
This is some text.

<!multipart type=alternative>
This is normal text.
<!part charset=iso-8859-1>
This ïs ISO text.
<!part type=text/enriched>
<center>This text is centered</center>
<!/multipart>

This is more text.

<!part type=image/gif filename="~/rms.gif"><!/part>

This is the final bit.
----------------------

But now all mail I send out is multipart.  Er.  Fix, fix.
