[Mark, you used non-RFC2606 names, the IESG will put a DISCUSS against
you.]

I agree but it is not the point: an email adress like
bortzmeyer+ietf at nic.fr is legal and works but not reliably (there are
many stupid broken Web forms which refuse it and tell me it's not
valid).

http://example is legal and should work. If it does not, it may
indicate a broken implementation.

There are many broken mail configurations.

No. A TLD is a domain like any other and we should not write special
rules for them.

I hate special cases.
