I notice some of the headers in messages we send out are not properly Capitalized. 

E.g. 
 - x-mozilla-news-host
 - user-agent
 - mime-version

They should of course read User-Agent, MIME-Version etc.

I assume this is fallout from jsmime.
Does it matter? MIME-headers are supposed to be case-insensitive.
MIME headers are case-insensitive; jsmime itself should be spitting out the headers for unknown headers (e.g., user-agent) in whatever case you sent it, but I believe we're normalizing to lower case within the compose backend because we don't have an easy case-preserving-but-insensitive map type.
Yes of course they are case-insensitive per spec. That doesn't make it less ugly.

Do you have a ref to where it all happens?
If we don't know, we should normalize to Upper-Cased like most headers would like to be. MIME-Version is a one off, but should be known.

Add a few other known headers, and make the default headers names Upper-Dashed-Camel-Cased.

These headers need to be added to the test_structured_headers.js and test_structured_header_emitters.js tests.

Please remove this line. Message-ID needs its own separate treatment, and unstructured isn't appropriate.

I feel like this needs test support as well.

Doesn't it end up being treated that anyway at the moment? It's only added to cater for the proper (special) capitalization. So should I just add parseMessageID and writeMessageID functions as placeholders that call parse/writeUnstructured?

I'm still not happy about adding the Message-ID stuff just to say Message-ID instead of Message-Id...

Nit: move the Message-ID related headers to their own block after the Date headers. (Message-ID headers will eventually constitute their own kind of headers.)
