A very very bad example of how not to retire a rbl.
What they did was just list the world and let everybody suffer with it. This is
just a very malicious act and not now things should have executed at all.
While I agree, I found 5 tickets in our system from 2025/02/14 (3 weeks ago)
regarding different servers who used NIXBL.
So, they did do more than just this.
Yes, I guess they should have followed RFC 6471 section 3.4 by e.g.
pointing NS to TEST-NET (192.0.2.0/24)

We have landed on the following DNS blacklist with our mail servers:
“ix.dnsbl.manitu.net <http://ix.dnsbl.manitu.net>”. This is reported by our
monitoring system (Nagios).
According to the website, this blacklist has been out of service since January
2025.
Now our question, how can it be that we still end up on this list and how can
we have ourselves removed again?
no chance - as it appears, Manitu/Nixspam has gone berzerk:

Hello List
I'm aware Manitu/Nixspam shut down a while ago, but iirc they promised RFC
compliant slow shutdown. As of today we see an increased number of rejects due
to Manitu listings. A quick lookup of some samples indicates that
ix.dnsbl.manitu.net is returning 127.0.0.2 for every query. Thus any mail
administrator still querying that list results in their clients having a very
quiet inbox today...
Can anyone confirm? Is there a statement from Manitu?
And as it appears the entire of Berlin's public service might have a quiet
friday today in terms of inbound external email - that's how I got to notice
this failure.
