So, do I understand correctly that, because one obscure non-RFC compliant e-mail address has been out there for a decade this is enough of a test to guarantee, there will be no issues with the current market leading MUAs and MTAs (and legacy ones) ?
There will certainly be issues with MTAs and MUAs, since there are plenty of them that implicitly or explicitly assume that every domain name contains a dot. What we do know is that the existence of such addresses doesn't cause any global problems. Why does this issue need the ALAC's limited time, rather than being just one more minor question for the purchasers of new TLDs to deal with? If they'll be spending $100K or more on their new domain, I think it's reasonable to assume that they can do their own due diligence. R's, John
