I like this idea a lot: I don't think this needs to be a per-project setting, however. There's only one "entry point" for submitting patches - parsemail.py - so a flag on this application would be more than adequate for limiting access. This will remove the need for the database migration. What are your thoughts on adding this flag in place of the project setting?
