## email
- plain text content only, with everything else being handled by metadata and headers
- no auto quoting -- quoting should be intentional
- no signatures -- that's just extraneous. at the very least signatures should be dynamic instead of static?
- username / password can be used for actor authentication via oauth? logging into an ap client should be like logging in with google?
