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 Netcore Cloud?

Netcore's feed remains a demand-generation channel; ten entries, zero product releases.

Nothing in this window is a product release. The feed publishes comparison pages, vertical funnel diagnostics and case studies, in clusters — four posts inside two hours on August 14, two more in the following days. Netcore appears in its own platform rankings, which is the point of the format. Engineering cadence and product direction cannot be read from this source at all.

mailcow vs Netcore Cloud: 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.

N5.0

Netcore's feed remains a demand-generation channel; ten entries, zero product releases.

◆ Current state

Nothing in this window is a product release. The feed publishes comparison pages, vertical funnel diagnostics and case studies, in clusters — four posts inside two hours on August 14, two more in the following days. Netcore appears in its own platform rankings, which is the point of the format. Engineering cadence and product direction cannot be read from this source at all.

◆ Where it's heading

The publishing operation is industrialised and aimed at buyers already comparing vendors: category-definition pages, head-to-head buyer's guides, and vertical breakdowns for real estate, hospitality, automotive and ecommerce, most using India-specific funnel data as the credibility hook. The one structural shift visible is a move from pure listicles toward customer-outcome stories, with the media-house newsletter case study framing an existing capability as new revenue rather than new function. Any velocity signal on this product reflects blog output, not shipping.

◆ Prediction

Expect the same weekly cluster of comparison and vertical-funnel posts, with Black Friday framing increasing through the autumn — the pre-BFCM email deliverability post is the first of that seasonal run.
