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.

What is Textellent?

Textellent leans into franchise SMS compliance with always-on 10DLC monitoring.

One genuine product announcement anchors the feed: always-on compliance monitoring and franchise-wide 10DLC handling, plus a brand-wide Do Not Text control aimed at multi-location systems. The rest of the crawled entries are SEO articles — SMS tax rules, text abbreviations, delivery-status explainers, and a Twilio-alternatives roundup — carrying no product change.

mailcow vs Textellent: editorial side-by-side

M
mailcow
COMMS
5.0

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.

T6.3

Textellent leans into franchise SMS compliance with always-on 10DLC monitoring.

◆ Current state

One genuine product announcement anchors the feed: always-on compliance monitoring and franchise-wide 10DLC handling, plus a brand-wide Do Not Text control aimed at multi-location systems. The rest of the crawled entries are SEO articles — SMS tax rules, text abbreviations, delivery-status explainers, and a Twilio-alternatives roundup — carrying no product change.

◆ Where it's heading

Textellent is positioning around the operational pain that carrier 10DLC rules create for franchises: registration bottlenecks and ongoing compliance risk across many locations. Continuous monitoring and network-wide controls suggest a move from point SMS tooling toward compliance infrastructure for multi-location brands.

◆ Prediction

Expect further franchise-oriented compliance features — centralized registration, network-wide opt-out and reporting — deepening the multi-location wedge.
