I use 
[htmldump](https://git.madduck.net/etc/mutt.git/blob/HEAD:/.config/mutt/htmldump) 
to render HTML mail to markdown, and then mutt's new 
multipart/alternative handling and [this 
script](https://git.madduck.net/etc/mutt.git/blob/HEAD:/.config/mutt/markdown2html) 
to turn markdown back into HTML on sending, and this will also take 
care of forwarded emails to a suitable degree.
