How to Find MFMailComposeViewController Email Addresses

One of the missing iOS APIs is a way to find out whom did user send email to. Otherwise MFMailComposeViewController is excellent: easy to setup, easy to launch, easy to use and easy to close. You just have no idea what user was doing with it!

I really needed to know who were email recipients. There are several good reasons for this and I just had one of those. So it was time to do some experimenting!
