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
