Not a direct answer, but a caution for the unwary:

Nothing you commit to the internet should be considered secure. Emails can be read by system admins, IP addressses can be traced (sometimes), that sort of thing. There are ways to check who's looking (we look periodically to see who has pinged our computers) & its sometimes interesting to see what you find.

Its that old saying: if you don't want to be held accountable for saying it, don't say it.
