mailcow vs Notion: at a glance
What is mailcow?
Six releases, and every one of them is a security update in some form.
mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.
What is Notion?
Notion is turning Custom Agents into event-driven workers with their own runtime and billing.
Almost every release in this window serves one construction: Custom Agents, the Workers that run code for them, and the surfaces they reach. Workers became shareable across a team in early July, gained usage tracking in the credits dashboard three weeks later, and the agents themselves picked up calendar tools and a dedicated iOS app. The single non-agent entry is a high contrast display mode.

mailcow
5.0COMMS
Six releases, and every one of them is a security update in some form.
◆ Current state
mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.
◆ Where it's heading
Two distinct pressures are visible. One is upstream: mailcow bundles Postfix, Rspamd, SOGo, nginx, unbound and Dovecot, so every one of their advisories becomes a mailcow release, and the base image migration from bookworm to trixie is that same maintenance surfacing at the OS layer. The other is the project's own web UI, where output escaping is being retrofitted view by view — quarantine table, sieve editor, queue manager, quarantine overview — which reads as a systematic pass rather than isolated reports. Earlier releases in the feed show where feature work went when it happened: forced 2FA, ACME DNS-01 challenges, and admin controls over EAS and DAV access.
◆ Prediction
Expect the monthly-plus-revisions rhythm to continue with upstream component bumps driving most of it, and the web UI escaping pass to reach the remaining admin views.
Notion
6.3PMCOMMS
Notion is turning Custom Agents into event-driven workers with their own runtime and billing.
◆ Current state
Almost every release in this window serves one construction: Custom Agents, the Workers that run code for them, and the surfaces they reach. Workers became shareable across a team in early July, gained usage tracking in the credits dashboard three weeks later, and the agents themselves picked up calendar tools and a dedicated iOS app. The single non-agent entry is a high contrast display mode.
◆ Where it's heading
The agent is moving from something a person prompts toward something the workspace starts on its own. Meeting note completion is now a trigger, so an agent can run without anyone opening a chat. Underneath that, Workers are being built out as shared infrastructure with an access model and a metered usage line, which is the shape of a platform rather than a feature.
◆ Prediction
Workers usage is now visible in the credits dashboard with the note that the beta will end, so paid metering for Workers is the clearly telegraphed next step. Expect more triggers alongside meeting notes as well, since one trigger type does not justify the trigger machinery.
