Add mail processing scaffolding

After receiving the email we don't want to process it in the same thread
as soon as we can, instead we queue it to a MailProcessor. This allows
us to be more flexible with the pipeline and reduce the amount of
concurrency for the database connection. This also helps with writing
possible fences around resource consumption.
