[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(_dot_)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.
I suspect there are still mail configuations
around that will re-write "user(_at_)tld" to "user(_at_)tld(_dot_)ARPA".
There are many broken mail configurations.
Should we be writting a RFC which states that MX and address
records SHOULD NOT be added to the apex of a TLD zone?
No. A TLD is a domain like any other and we should not write special
rules for them.
Should we be writting a RFC which states that single label
hostnames/mail domains SHOULD NOT be looked up "as is" in
the DNS?
I hate special cases.
