What does help is the record in reverse DNS (as in MTAMARK)
This ignores the reality of large ISPs, and all three network registries, of
being lazy in delegating and enforcing correct reverse DNS to begin with.
I know tech folks at major ISPs better then most people here and have
participated in RIR activities and know folks from all ip registries and
this statement is just not correct. All of them provide deligation of
reverse very promptly to their corporate customers & downstream ISPs (i.e.
T1s/T3s, dedicated ethernet, etc) and their tech folks will resolve the
problems quickly if anythhing is found. You're also ingoring the fact that
major ISPs are the ones who suffer the most from zombie spamming as their
infrastruture is abused and they have to deal with all the reports, I'd
bet the will be more then willing to participte and enter the records for
their dialup & similar dynamic customer pools.
I spoke over MTA MARK with APNIC and they seem to have no problems with
it. Most of the problems seem to arise from ISPs not willing to take
care of rDNS.
