Just a guess: did you configure Netscape as a mailer? Then it would of course know your e-mail address. I can't think of any other way for a browser to come up with an e-mail address that has a good chance of being the correct one.

Yes, but if I do not send an email from netscape, the site should not be capable of seeing my configuration in my Netscape.ini file?! If it can do that, there is much more to worry about.

It must be something else. Otherwise instead of stating that my email address is caal_p3.telepac.pt, it should be capable of saying what my 'real' email address is. I have a feeling it is some type of WHOIS service.

Anybody else any ideas?

A javascript (NOT java) program in a web page is certainly capable of instructing your computer to send email to another person *without you knowing about it*. From this email your true email address can obviously be found out.
