Chanty vs mailcow: at a glance
What is Chanty?
Chanty's feed is an HR statistics content mill, not a product changelog
Every entry in the window is a marketing article — referral, theft and satisfaction statistics roundups, plus a run of competitor-alternatives listicles published in a single batch. Nothing here describes a change to the messaging product itself.
What is mailcow?
mailcow's release notes are almost entirely upstream security currency.
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

◆ Current state
Every entry in the window is a marketing article — referral, theft and satisfaction statistics roundups, plus a run of competitor-alternatives listicles published in a single batch. Nothing here describes a change to the messaging product itself.
◆ Where it's heading
The publishing effort is going into search-driven HR and collaboration content aimed at buyers comparing team chat tools, with the alternatives posts targeting Slack, Yammer, Jive, Google Chat and Skype by name. Product direction cannot be read from this feed at all.
◆ Prediction
Expect more statistics roundups and comparison listicles; the feed gives no basis for predicting anything about the product.
mailcow
5.0COMMS
mailcow's release notes are almost entirely upstream security currency.
◆ Current state
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
◆ Where it's heading
For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.
◆ Prediction
Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
