Its not really a good title for it - its really proposing an IP/domain
link for authorisation of senders.

I'd say its a little early yet... there are 2 alternative DNS syntax
proposals there. I would prefer to have the RFC at least in a later
draft form before releasing any implementations.
Could anyone enlighten me how much needs doing to resolvers and DNS
servers to support this? I assume there will need to be some degree of
underlying infrastructure rehashing to allow this stuff to be produced.
[Unless you hack it into the TXT records]
However it looks to me as though it would be relatively easy to support
within exim acls. In the early stages though it might be better done as
a scoring mechanism in spamassassin - ie add 4 points for incorrect RMX
We do need to work out appropriate exim acl syntax.
