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 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms

Zoho Cliq is mid-cycle on its most substantial release in years. Cliq 7.0 (August 2026) introduced AI-powered thread summaries, automatic task extraction from conversations, voice transcription with AI notes, and a redesigned developer platform. The guest user feature was overhauled for external collaboration, and the product now runs natively on Neat conferencing hardware — moving from software into physical meeting rooms.

mailcow vs Zoho Cliq: 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.

Z6.3

Zoho Cliq 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms

◆ Current state

Zoho Cliq is mid-cycle on its most substantial release in years. Cliq 7.0 (August 2026) introduced AI-powered thread summaries, automatic task extraction from conversations, voice transcription with AI notes, and a redesigned developer platform. The guest user feature was overhauled for external collaboration, and the product now runs natively on Neat conferencing hardware — moving from software into physical meeting rooms.

◆ Where it's heading

Cliq is running a dual-layer play: embed Zia AI deeply enough in conversations that task tracking happens inside the messaging layer rather than alongside it, while simultaneously opening to the agentic ecosystem through MCP integration and a more accessible developer platform. The Neat hardware integration points toward a longer-term push for enterprise room-system budgets, typically owned by IT rather than team leads.

◆ Prediction

Expect deeper Zia integration within the Cliq developer platform — bots triggered by conversation context rather than scheduled tasks. The MCP path suggests Cliq is positioning itself as a target for external AI agents, not just a source of data for them.
