Thank you to use Pombo!
Then you will need to:
    1 - to enable encryption, import your GnuPG keyID
    2 - tune options into /etc/pombo.conf
    3 - tune variables into pombo.php
    4 - copy pombo.php to your server(s) (both PHP versions 4 & 5 supported)
And do not forget to write somewhere in security your computer Serial Number.
