This is a little more complicated than it sounds. First, the browser
must determine that SMTP is the delivery method that will be used for
that address, which is not necessarily anywhere accessible. Once you
know it's SMTP, you need to use DNS to look for MX records that point
to the preferred delivery site, where you can use VRFY.

In most cases this can be reduced to a VRFY, but it's
those exceptions that will get you....
