epriestley eabe3a4d33 Begin improving the soundness of received mail
Summary:
We/I broke a couple of things here recently (see D5911) and are doing some work here in general (see D5912, etc.).

Generally, this code is pretty oldschool and not especially well architected for modern application-oriented Phabricator. It hardcodes a lot of stuff which should be applications' responsibilites.

Take the first steps toward making it more solid to reduce the risk here. In particular:

  - Factor out the "self mail" and "duplicate mail" checks and add unit tests.
  - Make Message-ID hash handling automatic.

Test Plan: Ran unit tests.
