Chatmail relays for end-to-end encrypted e-mail

Chatmail relay servers are interoperable Mail Transport Agents (MTAs) designed for:

  • Convenience: Low friction instant onboarding
  • Privacy: No name, phone numbers, email required or collected
  • End-to-End Encryption enforced: only OpenPGP messages with metadata minimization allowed
  • Instant: Privacy-preserving Push Notifications for Apple, Google, and Huawei
  • Speed: Message delivery in half a second, with optional P2P realtime connections
  • Transport Security: Strict TLS and DKIM enforced
  • Reliability: No spam or IP reputation checks; rate-limits are suitable for realtime chats
  • Efficiency: Messages are only stored for transit and removed automatically
