It can also refuse to answer, or can assert that any address is valid.

It might verify a proportion of email addresses, but I can assure you
that it will also produce a not-insignificant proportion of false
positives and refusals to answer.  For all that I know, it could produce
false negatives also.  If you were a spammer, this may not matter.  If
you're a responsible internaut, then this does matter IMHO.
