This doesn't have anything to do with Perl (it's spelled "Perl"
if you talk about the language, and "perl" if you talk about
the binary. What "PERL" is, we don't know).
There is absolutely no relationship between HTTP and mail.
There's no magical way of finding out the email address
from someone posting a form - just as there isn't a magical
way of finding the email address of a person calling you.
How could there? Some people have upteen email addresses.
Others don't have any. And how is the form going to know
who sits in front of the screen anyway? People do share
computers and browsers (think for instance of the boots in
malls and airports). Only way to get a return address is to
ask the user - and hope they don't lie.
And just be very very glad there's no automatic way of
harvesting email addresses via web forms. Otherwise, your
amount of spam would tenfold.
