mailcow vs Element: at a glance
What is mailcow?
mailcow's November release patches an admin RCE and reworks sync jobs.
mailcow ships named monthly releases with lettered revisions, mostly to pull in upstream security fixes for SOGo, Nginx, Redis, Unbound and Rspamd. The November release goes further: it fixes a remote code execution flaw reachable by admins and domain admins, adds mailbox groups, and reworks imapsync so sync jobs reference a separate source. It also caps request bodies at 64 MB, which breaks large SOGo and ActiveSync mail unless NGINX_MAX_BODY_SIZE is raised.
What is Element?
Element 1.12.35 follows the call picture-in-picture release with one desktop storage fix.
Element Web spent October on crypto UX: mandatory device verification, removal of guest tokens and NEB links, and a shorter recovery-key flow in 1.12.33. 1.12.34 shipped OS-level picture-in-picture for Element Call, a module switch that disables public rooms, recovery-key generation when logging out of the last device and fixes for two security advisories. 1.12.35, a day later, backports a single fallback to synchronous safeStorage.

mailcow
5.0COMMS
mailcow's November release patches an admin RCE and reworks sync jobs.
◆ Current state
mailcow ships named monthly releases with lettered revisions, mostly to pull in upstream security fixes for SOGo, Nginx, Redis, Unbound and Rspamd. The November release goes further: it fixes a remote code execution flaw reachable by admins and domain admins, adds mailbox groups, and reworks imapsync so sync jobs reference a separate source. It also caps request bodies at 64 MB, which breaks large SOGo and ActiveSync mail unless NGINX_MAX_BODY_SIZE is raised.
◆ Where it's heading
The monthly security cadence holds, but recent releases carry more of mailcow's own features and API changes alongside the upstream bumps. Breaking changes now come with explicit migration steps, which suggests the API is being cleaned up for integrators.
◆ Prediction
Expect the promised RCE advisory details next week and a lettered revision within weeks to address fallout from the sync job API and body-size changes.
Element
5.0COMMS
Element 1.12.35 follows the call picture-in-picture release with one desktop storage fix.
◆ Current state
Element Web spent October on crypto UX: mandatory device verification, removal of guest tokens and NEB links, and a shorter recovery-key flow in 1.12.33. 1.12.34 shipped OS-level picture-in-picture for Element Call, a module switch that disables public rooms, recovery-key generation when logging out of the last device and fixes for two security advisories. 1.12.35, a day later, backports a single fallback to synchronous safeStorage.
◆ Where it's heading
Two tracks run in parallel: reducing key-loss failures in encryption, and giving deployers more control through the Module API. The public-room switch and timezone config point at managed and institutional deployments, while the new timeline in labs is slowly gaining parity features.
◆ Prediction
1.12.34 should ship stable within about a week, following the RC-to-release pattern of recent versions; read receipts suggest the new timeline is getting closer to replacing the old one.
