Comment:
We cannot use VRFY, since it is usually turned off for privacy and spam
reasons.
I think Michael's validator is probably something to put in the wiki and
point people to who want something more than the simple regular expression
and who are willing to wait for the DNS lookup (which can be slow and, as
Michael points out, fail temporarily). We are just trying to catch the
most fundamental errors with the reg-exp. If you really want to verify
that an email address is correct, send them an email and require a reply.
No core additions needed here, for those reasons.
