Doesn't it? IMHO, an empirically-founded method is likely to be a
better candidate for standardizing an anti-spam technique than a
purely theoretical work. After this rationale, e.g., I'll be
pondering on whether or not to propose
192.0.2.3.abuse-contact.arpa. TXT "abuse@xxxxxxxxxxx" [*]
based on the pros and cons that have been highlighted here, as well as
the interest that this topic seems to elicit.
[*] see http://www.imc.org/ietf-smtp/mail-archive/msg06625.html
(Actually, RIRs are rather skeptical on the effectiveness of this
tool. Quite few abuse-mailboxes are currently defined in the whois
databases, and their reliability will be worsen by making them
mandatory. The outcome of my pondering is currently "no".)
