Self Control is a free OSX application which blocks access to websites and incoming and/or outgoing mail servers for a predetermined period of time.
It gives you the ability to fine-tune your access. For example, you could block access to your email, facebook, and twitter for 90 minutes, but still have access to the rest of the web.
Once started, it can not be undone by the application, by deleting the application, or by restarting the computer – you must wait for the timer to run out.
