Hello everyone, We have landed on the following DNS blacklist with our mail servers: “ 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 :-) Best regards from Berlin (Germany). Lars Bornemann reventix GmbH
