mailcow vs Zoho Cliq: 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 Zoho Cliq?
Zoho Cliq is opening its bot platform to AI coding agents through MCP tools.
Cliq 7.0 shipped in August with AI summarisation, a developer platform refresh and Cliq Mini embedded across Zoho apps. September added reworked guest access, Cliq Rooms on Neat hardware and per-role subscription plans. In October Cliq published MCP tools for its developer platform, so automations can be generated with an AI coding assistant instead of written by hand.
mailcow vs Zoho Cliq: editorial side-by-side
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.
Zoho Cliq
6.3COMMS
Zoho Cliq is opening its bot platform to AI coding agents through MCP tools.
◆ Current state
Cliq 7.0 shipped in August with AI summarisation, a developer platform refresh and Cliq Mini embedded across Zoho apps. September added reworked guest access, Cliq Rooms on Neat hardware and per-role subscription plans. In October Cliq published MCP tools for its developer platform, so automations can be generated with an AI coding assistant instead of written by hand.
◆ Where it's heading
Cliq is turning into the messaging layer of the Zoho suite and widening its reach: other Zoho apps, meeting-room hardware, external guests, and now AI agents that write its automations. The developer platform keeps lowering the cost of building bots and workflows, first through 7.0's low-code tooling and now through MCP. Pricing is moving the same way, with role-based plans meant to put more of each company on Cliq.
◆ Prediction
Expect more of the Cliq developer platform (bots, handlers, widgets) to be exposed through MCP. The entries don't show whether AI-assisted building will be priced separately.
