DoubleTick vs mailcow: at a glance
What is DoubleTick?
WhatsApp-commerce blog feed is stale — newest entry is late 2024
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
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.

WhatsApp-commerce blog feed is stale — newest entry is late 2024
◆ Current state
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
◆ Where it's heading
The content positions DoubleTick around WhatsApp marketing and sales enablement, but with no 2025 or 2026 entries the trajectory is indeterminate — either the blog stopped updating or the crawler is pointed at an archived feed.
◆ Prediction
Without fresh entries no confident prediction is possible; the feed source most likely needs re-pointing to current content.

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.
