My function will quickly deny those because the DNS lookup for them will
immediately fail. Will your regex deny 'bogususer@bogusdomain.com'? Should
it?

That's your world. Mine is much simpler. :o) Seriously, I think Ben and
Manuel have it right. A combination approach is probably most effective
(and complex). I was hoping for a simple solution for the regex challenged.
Of course the old tried and true validation email that requires the user to
validate himself is the most fool-proof method, but thats not an on-the-fly
solution.
