MailMum is a self-hosted, privately-managed DNS blacklist (DNSBL) and mail-traffic audit log for organizations running their own mail infrastructure. It is all in your hands.
This blacklist is fundamentally different, because you will be able to create, maintain and control it yourself. We have been running this system for over 14 years (since 2012) as freelance admins and decided to make it a public product because it provides such valuable services for us.
