Changelog

In 2.8.x, we focus on improving stability for mail systems, expanding business workspace capabilities, and upgrading our infrastructure.

Integration and Security

We integrated Cloudflare Turnstile into the sign-up verification process to enhance security.

Account protection was strengthened across the board. We added account confirmation flows, normalized account casing, and enhanced email validation for sign-up.

Anti-Spam

We improved our anti-spam capabilities with enhanced mail authentication tagging, strengthening our ability to detect and handle suspicious incoming mail.

Business Workspaces

The business user experience has been significantly upgraded.

We introduced a new concept “TinkMail Business Workspace”, this allows businesses users to better understand the scope of our business offering. Also, we refactored the sign-in and sign-up flows for business users.

Mobile Experience

We have optimized the inbox view for mobile devices, now you can read your emails more comfortably on smaller screens. Documentation pages have also been enhanced to support better mobile layouts, including functional sidebar overlays and horizontally scrollable tables.

Infrastructure Improvements

We migrated our production infrastructure to a more robust setup. This provides better resilience, self-healing, and scalability to support our growing user base.

We have added a Backup MDA service, which removes the dependency on the central TinkMail foundation for mail delivery.

This service can be deployed independently, providing enhanced reliability and flexibility for mail handling.

Mail Sending Reliability

We have also refactored the mail sending process in the MTA to implement an retry strategy.

This ensures that outbound emails are delivered more reliably, even in the face of transient failures.

Monitoring and Alerting

Monitoring and error reporting have been enhanced.

Now from the foundational services such as databases and message queues, to the application layer, we have comprehensive monitoring and alerting in place to promptly identify and address issues.

In the web application, we also improved error capturing and reporting, for both client-side and server-side errors.

These improvements help us maintain a high level of service availability and performance. And we will be notified immediately when issues arise, allowing for swift resolution.

IMAP MOVE Command Support

Additionally, we have implemented the IMAP MOVE command, allowing users to move emails between folders more efficiently.

In the process, we have also added a new notification system to enhance IMAP synchronization when mails are moved.
