Actually submit has two purposes:

- If a client is in a position where it knows that its messages are not
  up to snuff, it can ask the MTA to help out.
  Some reasons have been given.
- If a server is faced with a message that is not up to snuff, the
  document says what it makes sense to do to it, and when.
  (Chapter 5)

We could have written this as only the latter, giving no SMTP extension,
but this would be highly distasteful to me, since we're essentially
providing a license to mangle messages "by the standard" without giving
any way to deterministically turn this processing off and on, so we would
be sanctifying a situation where we depend on heuristics.

(The next version will contain a "RELAY" keyword for MAIL FROM in order
to turn the processing OFF)
