DroneBL tracks IP addresses associated with botnets, drones and abusable services such as open proxies. A listing usually points to a compromised or abusable host; delist through its web lookup after cleaning up.
Why an IP gets listed on DroneBL
Blocklists add an IP when they see evidence of spam or abuse from it: mail hitting spam traps, a compromised server sending on behalf of a botnet, an open relay or proxy, or a sudden spike in unsolicited mail. Shared hosting and cloud IPs can also inherit a bad reputation from a previous tenant. It has moderate adoption; a listing may affect some receivers but rarely causes a broad delivery failure on its own.

Delisting only sticks if the root cause is fixed first. Run the full Mail Health Report to catch the SPF, DKIM, DMARC or reverse-DNS problems that often cause listings.
