Feb 1, 2026February 2026: Delivered Message Forwarding Enhancements for chatmail/core, achieving measurable performance and reliability gains for both intra- and cross-account forwarding. Intra-account forwarding now avoids duplicate BlobObject work when source and destination blob directories are identical, reducing overhead. Cross-account forwarding now supports HTML content, handles long messages, and persists HTML immediately to the database to preserve integrity even if the original message is deleted. These changes reduce processing time and resource usage while improving data consistency. Technical contributions include streamlined blob handling, robust HTML content management, and safer cross-account data flows, with co-authored input from Hocuri.

Nov 1, 2025Month: 2025-11 — chatmail/core Overview - This month focused on strengthening connectivity, optimizing data flow in group conversations, improving reliability and feedback, clarifying API behavior, and expanding test coverage and documentation. Delivered work emphasizes business value through more reliable messaging, reduced bandwidth, clearer API semantics, and faster performance on large IMAP-backed workstreams. Key features delivered - Real-time connectivity improvements: enhanced TURN/ICE handling with fallback servers and prioritization of available TURN servers to improve connectivity and reliability across networks. Commits include: 28fc1d2ff2165e31dc091834691f20ad5a32b4fa (fallback TURN server), f6817131b821f4c630e4c6b4eb8080ea2b83944a (avoid fallback if TURN from IMAP METADATA), 1ea8ed6442da0f14f6965b73187463aaa78ad957 (fallback ICE server when IMAP METADATA unavailable). - Group messaging efficiency and grouping logic: introduced a group consistency algorithm to prevent unnecessary group message downloads and enhanced To-field addressing using ad-hoc groups for duplicates. Commits include: 0f14edd5d90846b64b0a79a1afc2fa23e2890ef4 (Do not download group messages unconditionally), 6514b4ca7f23c7e42afd19c64a869a6f4b07f191 (Look up or create ad-hoc group for duplicates), 9305a0676c807223d523ba646e81e98cb048e59d (Assign outgoing self-sent messages to ad-hoc SELF groups). - User feedback and reliability improvements: improved user feedback with an error toast for old broadcast QR issues and ensured reliable ContactsChanged events after updates. Commits: fdea6c8af32238d7de47ab2a93b7048a86e14d64 (Error toast for open QR issue), d44e2420bc5143411ac3bb30cdaf79a6aea60362 (Emit ContactsChanged after transaction completion). - API clarity and policy changes: clarified color handling when keypairs are missing, deprecated database encryption in favor of filesystem encryption, and added targeted indices for performance. Commits: c499dabbe1e9f2d336292483a95b9ebdbc2ebb17 (Add get_or_gen_color), ba3cad6ad6f3ac92d3e345223e0e4e4eed27a159 (Docs: deprecate db encryption), 2854f87a9dfdf26a8b125817e23b6f3eaeb4a546 (CREATE INDEX imap_only_rfc724_mid). - Test coverage and documentation improvements: expanded tests for unencrypted group handling and related edge cases and added minor docs/format notes. Commits: 1dbcd7f1f40da785b309beec56a08f90ae94efe0, 7f059140be2f1b74a6844a53bd375f69550323a4, ef61c0c408e20261d232688d765494ccb50c4c79. Major bugs fixed - Connectivity fallback logic: ensured fallback TURN/ICE servers are used only when needed, and not when TURN servers are available from IMAP metadata, reducing failed connection attempts. (Related commits: 28fc1d2..., 1ea8ed64...) - Grouping and routing correctness: fixed group member handling for duplicates in To, ensured ad-hoc groups are used for outgoing self messages, and corrected test coverage around unique Message-IDs. (Commits: 0f14edd5..., 6514b4ca..., 9305a067...) - Reliability and event emission: fixed flaky updates by emitting ContactsChanged after transaction completion and added user-visible error handling for QR generation on older broadcasts. (Commits: fdea6c8a..., d44e2420...) Overall impact and accomplishments - Improved user-perceived reliability and connectivity across networks, with fewer connection failures and faster message delivery in real-time conversations. - Reduced data transfer and processing for group conversations through a group consistency approach, improving performance on larger groups. - Clearer API semantics and better guidance on security practices, alongside targeted database indexing, contributing to maintainability and performance. - Higher quality with expanded test coverage and documentation, reducing regression risk and easing future changes. Technologies and skills demonstrated - Networking and real-time communication: TURN/ICE, fallback strategies, IMAP metadata integration. - Data modeling and grouping algorithms: group consistency logic and ad-hoc group handling. - Reliability engineering: robust error handling, event emission, and user feedback mechanisms. - API design and security posture: color handling, encryption policy deprecation, and indexed queries for performance. - Testing and documentation: comprehensive test coverage for edge cases and accompanying documentation notes.

Sep 1, 2024September 2024: Strengthened authentication feedback and encrypted-message reliability in chatmail/core. Delivered two focused changes: - User Password Notification Flow Improvement: ensure NotifyAboutWrongPw is configured before saving, enabling prompt user alerts about authentication issues (commit 33cae2815d8aad5f6499833369dcd7efb4e20454). - MDN Handling for Not-Downloaded Encrypted Messages: prevent MDNs from being sent until the message is downloaded and ensure proper state updates post-download (commit eabf1d15b7492585873e2dc3ae64168dd786a0e5). Added tests to validate not-downloaded-message behavior (commit eabf1d15b7492585873e2dc3ae64168dd786a0e5; #2970). Impact: improved user experience during authentication, reduced noise from incorrect MDNs, and increased reliability of encrypted-message workflows. The work enhances security posture and provides clearer traceability via commit-level changes.

Aug 1, 2024In August 2024, chatmail/core delivered targeted IMAP folder handling improvements to increase reliability and data integrity. Key changes hardened folder existence checks, ensured seen-status processing only applies to existing folders, and prevented creation of non-existent folders during IMAP operations. The changes were implemented via a code fix that removes references to non-existent folders in imap_markseen (commit 3d9aee1368566474fd257e1c71f93ef9ccfa8206) under PR #5870. Business impact: reduced error states in IMAP workflows, lowered risk of corrupted folder states, and decreased support overhead. Skills demonstrated: IMAP protocol handling, defensive coding, commit-driven development, code review and collaboration.

Nov 1, 2023Delivered cross-device chat deletion synchronization in chatmail/core (November 2023). Implemented a new delete-with-sync method and updated existing deletion logic so deletions on one device propagate to all devices, enhancing data consistency across mobile and desktop clients. No major bugs reported; the change reduces orphaned chats and improves user experience, supporting future multi-device features. Technologies demonstrated include cross-device synchronization design, API/SDK integration, and updates to the persistence layer.
