Services Roadmap

Active

• Active SessionsGive the user a view on their active sessions and allow them to end the session.
• Thundermail: WebmailWhat would an email service be without webmail? We will spend time making the proof of concept more usable, and enable this as an experimental feature for users willing to try new things early. The scope will initially be limited to basic folder visibility and message display.

Planned

• Improve Thundermail Add-on IntegrationWe are shipping an add-on that enables Thundermail features in Thunderbird desktop. To keep the barrier to entry low, we want to improve integration by using the system add-on or the new account add-on mechanism. This makes these features easier to discover and use within Thunderbird.
• Import email, contacts, and calendar featureAs one of the top ideas on ideas.tb.pro, we have added this suggestion from: https://ideas.tb.pro/p/import-email-calendar-and-contacts-feature and it fits into our quest to make Thundermail the users’ primary inbox.

Shipped

• MFA SupportMultifactor authentication via TOTP or a similar method is an essential security feature.

• Thundermail: Spam FilteringThe spam filtering was very aggressive, causing many emails to unintentionally land in the spam folder. The filtering mechanism has been changed to significantly improve this behaviour. A big thank you to Mauro and team from Stalwart, who have made the spam detection algorithm more sophisticated and accurate!
