Please either remove or allow me to opt-out of arbitrary messages from other users

See https://extranet.atlassian.com/display/~rackley/2013/03/11/Bitbucket%2C+please+remove+this+feature

I'm happy for you to give my email address to other Bitbucket users instead.

The problem isn't that I don't want people contacting me. My problem is with the absolutely terrible notification emails with no indication of who they're from or how to reply and you forcing me to use your internal email-like client to reply.
