About this directory

Each entry links to a page with public facts about that mail server: the IPs it resolves to, its reverse DNS and forward-confirmed rDNS, any detected software, and blocklist (DNSBL) reputation. A server appears here only after a domain that uses it has been checked. We never actively scan mail servers - all of this comes from public DNS or data already collected.
