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 recent entries are blog content, not product releases — the signal is a BFSI and ecommerce vertical sales push.

All visible entries for Netcore Cloud are blog posts — covering Indian financial services (Muhurat trading, SIP lapse prevention, insurance renewal CTR), DPDP compliance positioning, and ecommerce personalization — rather than product changelog entries. The platform's Journeys product appears as the execution layer across these verticals, but no feature releases are visible in this dataset. Netcore appears to be in an active content-driven sales motion rather than a public product release cycle.

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 recent entries are blog content, not product releases — the signal is a BFSI and ecommerce vertical sales push.

◆ Current state

All visible entries for Netcore Cloud are blog posts — covering Indian financial services (Muhurat trading, SIP lapse prevention, insurance renewal CTR), DPDP compliance positioning, and ecommerce personalization — rather than product changelog entries. The platform's Journeys product appears as the execution layer across these verticals, but no feature releases are visible in this dataset. Netcore appears to be in an active content-driven sales motion rather than a public product release cycle.

◆ Where it's heading

Netcore's content output signals a concentrated bet on regulated Indian industries (BFSI) and ecommerce personalization. The DPDP compliance article positions the platform for deals in post-DPDP enterprise India; the financial services-specific content points to a vertical sales expansion rather than a product evolution. The email deliverability content (Postmaster Tools V1 retirement) suggests Netcore is also defending its core email deliverability positioning against market changes.

◆ Prediction

Without product release entries, predicting specific features from this data isn't possible. The DPDP compliance angle and concentrated BFSI content suggest Netcore is in a sales expansion phase targeting Indian enterprise financial services customers in the near term.
