Hello,

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?
Thank you in advance and have a nice day :-)
judging from posts here and on other Postfix lists, NixSpam currently
seems to reply with false positives. Just read it myself and didn't
investigate further, but NixSpam has been shut down for a few weeks already.
Seems current rspamd has it disabled already, on older versions you can
remove it manually. Of course doesn't help if you can't send.
Florian
