Pluto2 is an anonymous SMTP relay server designed for Tor hidden services with advanced protections against traffic analysis. It implements replay attack prevention with 24-hour MessageID cache, timing attack resistance through cryptographically randomized delays, size correlation resistance with mixnet batching in 30-second windows, and traffic analysis resistance via automatic cover traffic to Gmail addresses. It includes per-IP rate limiting, RFC-compliant email validation, mail2news gateway support with equal sign in local part, and relay policy exclusively toward onion domains via Tor. It accepts senders from any valid domain and recipients on onion or clearnet with verified MX records, but relays only to onion addresses on port 25 without metadata retention, smtp://dgayvmsxvvofpdxsas22fo7eu5tous6aavzjs6eun6jnouluwqflz7ad.onion .
