- Bridge Node Support: Added functionality to manage mail (send/receive) on remote nodes via a bridge node. Full transparent management requires a private key on the bridge, while the remote node can operate with only a public key. - End-to-End Encryption (E2EE): Integrated E2EE using age. Encryption and decryption occur strictly at the bridge level; node administrators cannot access message content. - New Addressing Schema: Transitioned from nodepub@yggmail to userpub@nodepub. - Key Adaptation: Implemented ed25519 to x25519 coordinate adaptation, allowing signing keys to be used for encryption. Changed - Address Encoding: Switched from hex16 to base32 for the address space. - Memory Optimization: Replaced direct memory allocations with streaming for mail processing to reduce RAM overhead. - Code Refactoring: Performed decomposition of the original inherited codebase to improve maintainability. Fixed - Mail Updates: Fixed the mail retrieval mechanism to ensure near-instant updates for incoming messages.
