Does Netscape Navigator let servers see my email address?

Versions 1.0 and later of Netscape Navigator do not let web (HTTP)
servers see your email address.  Pre-release versions of Netscape
Navigator before 1.0 used to let servers see your email address, but
then we discovered an admin who was using this to send junk mail to the
people who were visiting his site, so we removed this feature.
Web servers are able to see that you are connecting to them with a copy
of Netscape Navigator (because it identifies itself as such), and they
are usually able to see what computer system you're connecting from, but
no other information about yourself is given.
Note that there is a field in the "Mail and News" section of the
Netscape Preferences where you can give your email address, but this is
used only to put your return address on outgoing email you send from the
Navigator, and it is not given to any web servers you visit.
Version 1.x of Netscape Navigator sends your email address as the
password when you do an anonymous ftp to an ftp server.  Version 2.0 of
Netscape Navigator always sends "mozilla@" as the password instead.
