Wouldn't it be simpler to support MTAmark instead of some naming

Claus, you are correct, provided MTAmark is implemented. What is the
status of MTAmark? MTAmark seems to be a modification of the DNS
specification, so how long before everyone's BINDs get up to date?
Last time I looked, MTAmark needed only a couple of TXT records. No
change of DNS or BIND necessary.
To be really honest, I'm small fry. I don't do my own DNS -- I let my
registrar do it. And the interface they have doesn't seem to allow for
TXT records.
You aren't the only one. My ISP doesn't delegate reverse DNS for /29
networks, so I couldn't implement MTAmark for my home network myself but
need my ISP to do that. (OTOH, maybe that isn't that bad - let ISPs
publish MTA=no indications for their whole range and customers who want
to run their own MTA have to explicitely tell their ISP).
