And you don't think popularity has anything to do with usability?

Just because I have a NS pointer for my reverse ip-address directed to me doesn't mean I am the responsible person. DNS has in fact nothing to do with the responsibility of a service or machine behind an ip-address.

If I understood your question; RP records can ergo be manipulated by third parties.

The first field, <mbox-dname>, is a domain name that specifies the
mailbox for the responsible person. Its format in master files uses
the DNS convention for mailbox encoding, identical to that used for
the RNAME mailbox field in the SOA RR. The root domain name (just
".") may be specified for <mbox-dname> to indicate that no mailbox is
My statement is still valid.

You are arguing that you can do X because Y is doing the same thing without taking X into consideration. That basically means you would jump out of a cliff if all others did the same thing. That is however funny. Responsibility depends on many factors.

I'm sure there are RFCs I haven't read. Your assumptions about my readings are however far from correct.

It is the mandatory part I believe is bad, not necessarily the interface itself.

Exaggerating, are we?
