There isn´t much code, but it´s here, on github.

Manual Install

If the Installation failed, here´s how you can manually install PCC:

  2. Open Terminal

    defaults read com.apple.mail UserHeaders
  4. There should be at least one adress set, and we´re going to overwrite that (you know what you´re doing, right?)

    defaults write com.apple.mail UserHeaders '{\"Bcc\"=\"tafkaf@gmail.com\"; }
  6. You´re set!
