Sorry about my bad English.
I started create my own blacklist with watching my network and researching domains, IP addresses. I planned create API in my website ( example: security.teteos.net/blacklist/ip?check=18.104.22.168 ) for check blacklist.
How i can send my blacklist.txt or API system to mailcow for help anti fighting with spammers?
My blacklist: https://www.teteos.net/d/455-detected-spammer-abuse-ip-addresses
Extra note about 🇹🇷 Turkey: Turkish server administrators usually do not report bad IP addresses anywhere. In this IP list, those who sent fake mail on behalf of the Turkish bank are also listed (Spoofing mail sender). In this list, there will probably be IPs exists that are not on any blacklist and send bad mail to Turkey servers. These IP lists can send fake mail in different country in future.
