Add a note on email encodings

Leave a note for future devs that the server might receive an email with
an encoding different from ASCII or UTF-8. This can be problematic as
String accepts only UTF-8 valid strings.

In TODO when I say "handle non UTF-8 encodings", I think it would be
totally ok to just disregard anything that isn't UTF-8 and return a
"rejected for policy" error to the MTA. Otherwise we'll just have to put
`encoding_rs` in the mix.
