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 MessageMedia?

MessageMedia is folding into Sinch Engage, sunsetting a 20-year brand.

MessageMedia is an Australia/New Zealand business-messaging provider acquired by Sinch in 2021. Its feed is mostly older SMS-marketing blog content, but the current news is a rebrand: from 28 July 2026 the product becomes Sinch Engage, with the company saying the product, mission, and team stay the same.

mailcow vs MessageMedia: 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.

M3.8

MessageMedia is folding into Sinch Engage, sunsetting a 20-year brand.

◆ Current state

MessageMedia is an Australia/New Zealand business-messaging provider acquired by Sinch in 2021. Its feed is mostly older SMS-marketing blog content, but the current news is a rebrand: from 28 July 2026 the product becomes Sinch Engage, with the company saying the product, mission, and team stay the same.

◆ Where it's heading

The rebrand completes the absorption of MessageMedia into Sinch's global messaging brand that began with the 2021 acquisition. The direction is consolidation, presenting local messaging expertise under one global identity, rather than a change in capability.

◆ Prediction

The next likely move is the rebrand going live on 28 July 2026, with product and domain assets migrating to the Sinch Engage identity.
