MTAMARK:
It suffers from the fact that reverse DNS lookups are

What? "reverse DNS lookups are poorly implemented"? What the hell are
they talking about? I think they are talking about managing revDNS is
currently *neglected* ... wow, but managing XML records in DNS does
Has someone contacted any big ISPs to see whether they are willing
to implement MTAmark? If none of the ISPs that host spam zombies
(from which 80% of the spam originates according to some recent
report) right now will participate then it seems the proposal won't
be useful. AFAIK several big ISPs have been approached and have
not shown any interest.
PS: I sent this question to Markus directly in March but haven't
heard back (probably eaten by some spam filter...)
