V26.9.1 Release Notes

Deployed: 16 September 2026

Written by Andre Klaus

Summary

This release introduces a new PWA-based viewer that opens in its own tab with a redesigned installation flow. Access-revoked emails now show a neutral "This email is no longer available" message rather than telling recipients their access was withdrawn, and the email portal drops its cap on replies. Sixteen bug fixes are included, covering attachment forwarding, large file handling, encrypted email rendering and several administration settings issues.
