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 Chatwoot?

Chatwoot added voice, then turned its AI agent loose on the conversations it already resolved.

Chatwoot spent years building text-first support — live chat, email, WhatsApp, social, help center — and in June added voice calls in beta, closing the last channel gap against the incumbent suites it competes with. Alongside that, Captain has moved from a reply assistant to something that acts: calling external APIs during a conversation, keeping its own document set fresh, and now proposing FAQs mined from resolved tickets. The rest of the release stream is agent-workflow polish — chatlist layouts, editor resizing, bulk help-center edits — shipped every two to four weeks.

mailcow vs Chatwoot: editorial side-by-side

COMMS
5.0

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.

C6.3

Chatwoot added voice, then turned its AI agent loose on the conversations it already resolved.

◆ Current state

Chatwoot spent years building text-first support — live chat, email, WhatsApp, social, help center — and in June added voice calls in beta, closing the last channel gap against the incumbent suites it competes with. Alongside that, Captain has moved from a reply assistant to something that acts: calling external APIs during a conversation, keeping its own document set fresh, and now proposing FAQs mined from resolved tickets. The rest of the release stream is agent-workflow polish — chatlist layouts, editor resizing, bulk help-center edits — shipped every two to four weeks.

◆ Where it's heading

Two arcs are running in parallel. Channel completeness is nearly done, so the differentiation is shifting to Captain, which is being built as a closed loop: it answers from a knowledge base, watches which conversations humans resolve, and feeds the gaps back into that knowledge base without anyone curating it. The help center is being rebuilt to carry that weight — a documentation layout, bulk reorganisation, editor and published output brought into alignment — because it is the substrate Captain reads from, not just a customer-facing page.

◆ Prediction

The obvious next step is letting Captain publish approved FAQ suggestions straight into the help center rather than handing back a review list, which would complete the loop end to end. Voice is still in beta and has no Captain story yet, so expect the two arcs to meet — transcription and Captain handling on calls.
