Re: [ietf-smtp] Dotless domains and email

An excellent suggestion! Who will write the first draft?

Depends whether the topic is "dotless domains suck" or the more
general but more important "local namespaces on the Internet and why
the global DNS has to stay out of them."

The problem with dotless domains and the problem with whatever.corp or
whatever.lan or whatever.local are really the same: these are
namespaces that have historically been informally managed on
innumerable private networks, often behind firewalls or NATs, and if
you try to use them as global domain names, Bad Things(tm) will
happen.

In both cases you can argue, more or less credibly, that it's sloppy
software that would never have done that if it strictly followed the
RFCs, and in both cases the reality on the ground is that it happens
and it's not going to stop.

R's,
John
