Klookie, once installed on your computer, checks regularly your e-mail account evaluating the subject-line of them. The response-mail will be generated automatically.
In this way you can request files of your computer via email or provide files of your computer for "download".
For your security:
The files and directories must be authorized explicitly
You can protect these files or directories with a password or a password-list.
Klookie only downloads the headers of the e-mails. So thereТ‘s no chance for Viruses, Worms and Trojans to enter.
