A small mail server that exists to receive, not send.
What it does
It accepts inbound mail for a couple of domains and exposes a simple HTTP API to create disposable inboxes and read their messages, with API-key auth, automatic expiry, and a long-poll endpoint for grabbing the latest OTP or magic link. A web inbox sits behind single sign-on for humans.
Where it fits
It backs test harnesses and data-generation tooling that need real, throwaway email addresses, plus the AI agents that run signup flows. Running our own means no rate limits, no third-party dependency, and full visibility into what landed.
