A one-binary mail server learning to behave like production infrastructure.
A side-by-side editorial comparison of mailcow and Trumpia — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Trumpia ships SMS explainers weekly and product notes never.
Every entry in this window is educational or promotional: emoji meanings, a KPI list, a drip-campaign definition, opt-in psychology, an RCS-to-SMS how-to, and a Forbes mention. There is no release note, version number, or feature announcement anywhere in the feed.

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.
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.

This is a top-of-funnel SEO program rather than a changelog, so it carries almost no signal about where the product is going. The mild topical drift is toward RCS and toward consent and compliance, which is where SMS vendors currently face the most pressure, but nothing here shows what Trumpia is building in response.
Expect the same cadence of definitional SMS posts to continue. Nothing in these entries supports a prediction about the product itself — that would need a source other than this feed.
