I think you are confusing client and server. A process needs
privileges to *listen* on those ports, but not to try to connect to
them. So, while an HTTP or mail server must be run under a privileged
account, mail and web clients do not need to be.

Supposedly, on OS X and Linux, you can't bind to a port # < 1024

ports < 1024. I've never had Safari ask me for my password (via the
login screen - like in certain control panels) every time I want to
surf the web. Ditto for Mail.app.
This doesn't seem to jive.
