Mailu vs Zoho Mail
A side-by-side editorial comparison of Mailu and Zoho Mail — release velocity, themes, recent moves, and the top alternatives to consider.
Mailu vs Zoho Mail: at a glance
What is Mailu?
A mail server whose entire visible output is patching other people's code.
Mailu is a self-hosted mail suite shipped as a Docker compose stack, and the 2024.06.x branch shown here is its maintenance line. Every release in the window is a single-issue patch — a Roundcube bump, a CVE fix, an autoconfig tweak. The cadence looks high at ten pinned releases in five months, but each carries one change.
What is Zoho Mail?
Zoho Mail is annexing the workday around the inbox: web tabs, tasks, and an MCP endpoint.
Zoho Mail's feed is mostly explainer and positioning content, but the product moves inside it all point one direction: the inbox as a container for the rest of the workday. Web Tabs pins third-party sites beside the mailbox, Zoho ToDo carries tasks, and an MCP endpoint opens the mailbox to agents. The enterprise layer around it — admin console, journaling, admin reports — is being documented and rounded out rather than rebuilt.
Mailu vs Zoho Mail: editorial side-by-side
Mailu
5.0COMMS
A mail server whose entire visible output is patching other people's code.
◆ Current state
Mailu is a self-hosted mail suite shipped as a Docker compose stack, and the 2024.06.x branch shown here is its maintenance line. Every release in the window is a single-issue patch — a Roundcube bump, a CVE fix, an autoconfig tweak. The cadence looks high at ten pinned releases in five months, but each carries one change.
◆ Where it's heading
Most of what Mailu ships is downstream maintenance of its bundled components, Roundcube above all, which drove three of these ten releases. The project's own work here is defensive: escaping user-controlled fields in generated sieve scripts, setting X-Forwarded-By, adapting to Microsoft's new autodiscover. This is a product in steady-state operation, where the release notes track what upstream broke rather than what Mailu decided to build.
◆ Prediction
The next pinned release will most likely be another Roundcube or Alpine bump, since component upgrades triggered half the releases here. These entries say nothing about what is happening on the main branch.
Zoho Mail
6.3COMMS
Zoho Mail is annexing the workday around the inbox: web tabs, tasks, and an MCP endpoint.
◆ Current state
Zoho Mail's feed is mostly explainer and positioning content, but the product moves inside it all point one direction: the inbox as a container for the rest of the workday. Web Tabs pins third-party sites beside the mailbox, Zoho ToDo carries tasks, and an MCP endpoint opens the mailbox to agents. The enterprise layer around it — admin console, journaling, admin reports — is being documented and rounded out rather than rebuilt.
◆ Where it's heading
The arc is consolidation rather than depth: instead of making email itself better, Zoho is absorbing the surfaces users leave the mailbox for. Two access paths are advancing in parallel — a human one through Web Tabs and ToDo, and a programmatic one through MCP and Client Scripting. The compliance and admin material signals who this is aimed at, and Microsoft's EWS retirement is being worked as a migration opening for displaced Exchange Online tenants.
◆ Prediction
Expect both paths to extend — more embeddable surfaces inside the mail UI, and more of the mailbox reachable through MCP and Client Scripting. The entries show no pricing or packaging changes, so which of these land in the paid enterprise tiers is unclear from this window.
