Good routine to have handy, but it doesn't deal with MX records, which
are increasingly a part of Internet life as more and more people use
virtual domains (like me!).
I've been thinking about this problem off and on since writing a response
yesterday, and have come to the conclusion that the only real way to
know if an email address is valid is to attempt delivery and wait for
the bounce; but given that this process could take quite a long time
(hours) depending on the depth of the mail queues involved or the
ultimate destination, that won't work well on a web site that is supposed
to be interactive.
