what is tempmail fr?

tempmail is a self hosted backend for running your own temporary email addresses on a domain you own, built with Go and a small embedded SQLite database so it needs no separate database server. It exposes a REST API for creating, checking, and deleting disposable mailboxes and their messages. The way it works is that you point your domain at Cloudflare and set up Cloudflare Email Routing so any address at your domain forwards incoming mail to one real relay mailbox, such as a Gmail, Outlook, or Firstmail account. The tempmail service does not sit there constantly checking that relay mailbox in the background. Instead, only when a client calls the API to check a mailbox's messages does the service reach into the relay mailbox over IMAP or Microsoft Graph and pull the relevant mail on demand, then route it back based on which address it was sent to. This on demand approach avoids wasting Cloudflare Worker usage and keeps the relay mailbox from being hammered with requests, since repeated checks within about a second are served from the local database instead of triggering a fresh fetch. For personal Outlook accounts the project recommends using Microsoft Graph rather than IMAP, since IMAP can be unreliable there, while Gmail and providers like Firstmail work well over plain IMAP with an app password. An optional webhook endpoint is also available for setups that prefer a push based Email Worker instead. The project can run as a plain binary, inside Docker with an image published to GitHub Container Registry, or as a systemd service, and tagged releases trigger GitHub Actions to build multi platform binaries and container images automatically. A typical use is generating a short lived mailbox to receive a single verification code, then polling the messages endpoint every one to three seconds until it arrives.
