I'm afraid that you will have to wait until someone invents a telepathic
computer, that will be able to accomplishing such an amazinf feat.
Until then, unfortunately, a number of inconvenient laws of physics of this
universe will prevent anyone from determining whether an email address is
deliverable without looking up its MX server, and connecting to the MX
server's port 25.
