RE: [mailop] IPv6 DNSBL

[David Hofstee <david () mailplus nl>]

I suggest reputation on the reply-to domain also (if authenticated of course). No more running to other IPs / ESPs if 
you are a bad boy. You can integrate it in browsers and show it there too (watch out; don't enter your email address 
here because they will spam you or have spam evading practices [if no authentication takes place]). Show the reputation 
in the email client if possible.

And I would like fine-grained complaining possible (so everyone can filter like the big boys can, one might need the 
'ham' numbers too). But you want to be sure such numbers are authentic.

Here Here..

(For instance, we recommend that people running filtering turn those off right away, eg SA..)

But we do see a lot of people discussing this here, and at the risk of making even more noise on this list on this 
subject, and maybe we should kill the thread there..

It would be interesting to get a poll of sorts.. hands please..
(You can reply off-list)

Options:

1) Only allow IPv4 to be used for MTA's
2) Create a Registry of Operators/IPs for MTA's on IPv6
3) Allow all IPv6 to be used for MTA's, and use blacklists
4) Other (Suggestions)

And if you believe in item 2, (personally I am happy with 1 or 2 and open to 4) what would you expect such a registry 
to look like?
