May 2026 monthly summary for the Chatwoot project highlighting contributions focused on expanding email inbox configuration capabilities. Delivered a non-breaking enhancement to configure IMAP authentication by adding an IMAP Authentication Method Selection (plain, login, cram-md5) with end-to-end support from UI to storage. Implemented frontend dropdown aligned with existing SMTP authentication patterns, backend API validation for allowed authentication types, and normalization to CRAM-MD5 across the stack. Updated the IMAP service to handle multiple authentication mechanisms and ensured compatibility with Net::IMAP. Added and updated tests (unit/integration) and documentation to reflect the new behavior, preserving backward compatibility. Overall, this work expands provider compatibility, reduces setup friction for customers, and lowers support load by delivering a robust, secure, and test-covered inbox configuration flow. Key business impact includes higher potential customer adoption, easier onboarding, and improved reliability for email-related features.
