And in some cases, it doesn't..... At home, every e-mail that comes in

matter whether it's addressed to me, root, etc.) starts with
From [EMAIL PROTECTED] .....
Mail delivery to my machine (except for one certain address that's
handled via POP) looks something like this:
incoming via UUCP --> sendmail --> procmail --> disk
At some point between the message being received via UUCP and procmail
actually starting to work with it, the original envelope "From " is
lost and is replaced with the one above. So basically, I wouldn't trust
it for anything.
