Pluto2 is an SMTP relay server designed for Tor hidden services with
strong anonymity protections. It accepts mail on .onion addresses and
relays to both .onion destinations and clearnet via Tor circuits.
Security features: mixnet batching (30s windows), cover traffic generation, replay attack prevention (24h cache), adaptive padding against size analysis, randomized delays, and no persistent metadata retention.
Supports RFC-compliant email validation, v3 onion addresses only, automatic
MX lookup for clearnet domains, and exponential backoff retry logic.
Written in Go. Static binary compilation. Suitable for mail2news gateways, anonymous mail relay, or Tor-only messaging infrastructure.
