A few years back I developed a simple filter that does, more or less,
what you're looking for. I believe it fulfills your first 5
requirements. I've not designed nor tested it with PGP signatures or
inline images.

It serves as a replacement to Mutt's sendmail command, it processes the
text using reStructuredText (that should be easily switched with
markdown), and the result is a multipart/alternative that contains the
original message as text/plain and a text/html.

I don't know how well it complies with standards, and I haven't tested
the resulted mail with all possible email clients. I believe it works
well with Gmail and thunderbird.

Hope it helps,
