Sendermap runs on your own machine — the client starts it, so there is no endpoint to ping. 864 installs a week from pypi. Last commit 24 Oct 2026.
Maps every service that sends email as a domain, with the public record behind each one.
Today is the operative word: we check Sendermap every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
