If a mail arrives with the 'X-Patchwork-Delegate' hint header, the
'patchwork.parser' script will need to index the users table to find the
appropriate user. This should be okay from a security perspective since
passwords are hashed and salted and the rest of the information is
mostly accessible publicly via the web UI and REST API.
