mailcow vs Melp: at a glance
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 Melp?
Melp's feed is programmatic SEO Q&A content, with no product signal to read
Melp is a digital-workplace and team-collaboration app, but its feed is entirely programmatic SEO content: question-shaped posts ('Which tool is best for X?', 'Most secure platforms for Y') and geo-targeted roundups that list Melp alongside Microsoft Teams, Google Workspace, and Slack. None of these are product releases; they read as search-capture articles built around the 'digital workplace' framing.

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.
Melp
5.0COMMS
Melp's feed is programmatic SEO Q&A content, with no product signal to read
◆ Current state
Melp is a digital-workplace and team-collaboration app, but its feed is entirely programmatic SEO content: question-shaped posts ('Which tool is best for X?', 'Most secure platforms for Y') and geo-targeted roundups that list Melp alongside Microsoft Teams, Google Workspace, and Slack. None of these are product releases; they read as search-capture articles built around the 'digital workplace' framing.
◆ Where it's heading
The visible strategy is SEO reach — positioning Melp as a broad digital-workplace alternative across security, scalability, and regional queries. That tells us about go-to-market and content volume, not product direction. Actual releases and versions are not present in this stream, so product movement can't be judged from it.
◆ Prediction
No release data is present, so a grounded product prediction isn't possible; the only forward signal is continued SEO content positioning Melp as an all-in-one digital-workplace platform.
