Hi their,
some time ago, i have write an Tutorial about GnuPG for sendEMail. You can read here (German): http://wiki.ipfire.org/de/optimization/scripts/gpg
It was about time to write this Tutorial in english. My english is not the best, so I would ask anyone to take this part for our "not German-speaking" peoples.
Thanks for help & a nice day!
BG, Thomas
