just fiddling with the header but mml apparently believed that it knew
better than i did what Content-Type header to send and sent out
text/plain anyway :/

Interesting, it does look plausible, though i confess i don't like the
idea of needing a two-stage pipeline. seems like a lot of attack surface
and moving parts :/
