What is Zoho Mail?

Zoho Mail annexes the workday around the inbox, with governance as the enterprise wrapper.

The feed is mostly explainer content, but a real product arc runs through it. Web Tabs is the launch in this window, pinning third-party websites inside the mail client itself. Around it sit enterprise-layer pieces: journaling for audit retention, an admin console walkthrough, and now a rules piece framed around catching a spoofed invoice before anyone acts on it.

What is Dovecot?

Dovecot's 2.4 rewrite is still being paid for — twelve CVEs across two releases, two of them 2.4 regressions.

Dovecot 2.4 broke configuration compatibility outright in January 2025 and the line has been stabilizing ever since. The last two releases are dominated by security work: 2.4.3 shipped eight CVEs including SQL and LDAP injection when auth_username_chars is empty — both labelled v2.4 regressions — and 2.4.4 added four more, among them a fakeable CRAM channel binding and an incomplete earlier fix. Alongside that, 2.4.4 permanently drops root privileges in indexer-worker, quota-status and script-login before they serve requests.

Zoho Mail vs Dovecot: editorial side-by-side

Z6.3

Zoho Mail annexes the workday around the inbox, with governance as the enterprise wrapper.

◆ Current state

The feed is mostly explainer content, but a real product arc runs through it. Web Tabs is the launch in this window, pinning third-party websites inside the mail client itself. Around it sit enterprise-layer pieces: journaling for audit retention, an admin console walkthrough, and now a rules piece framed around catching a spoofed invoice before anyone acts on it.

◆ Where it's heading

Consolidation is proceeding on two paths, one human and one administrative. Web Tabs and the Zoho ToDo coverage pull more of the workday into the mail window; journaling, admin reports, and rules build the control layer an enterprise buyer needs before consolidating anything. The newest post shifts the pitch from capability to control, which is how Zoho argues the enterprise case against Microsoft 365, with the EWS retirement worked as migration collateral rather than a product change.

◆ Prediction

Expect the next real launch to extend Web Tabs or the rules engine rather than open a new surface, and expect more governance-framed explainers around it. Whether the MCP endpoint becomes a genuine agent surface is not visible in these entries.

0.0

Dovecot's 2.4 rewrite is still being paid for — twelve CVEs across two releases, two of them 2.4 regressions.

◆ Current state

Dovecot 2.4 broke configuration compatibility outright in January 2025 and the line has been stabilizing ever since. The last two releases are dominated by security work: 2.4.3 shipped eight CVEs including SQL and LDAP injection when auth_username_chars is empty — both labelled v2.4 regressions — and 2.4.4 added four more, among them a fakeable CRAM channel binding and an incomplete earlier fix. Alongside that, 2.4.4 permanently drops root privileges in indexer-worker, quota-status and script-login before they serve requests.

◆ Where it's heading

The 2.4 line is a rewrite absorbing its own cost. Dependencies are being replaced rather than pinned — libicu swapped for an in-house unicode library, libpcre2 brought in for regular expressions — and the process model is being tightened, with permanent privilege drops and a reworked service_reuse_port that pre-creates one socket per process. IMAP4rev2 and UTF-8 mail remain behind build flags and config toggles, so the modern-protocol work is real but deliberately unshipped.

◆ Prediction

Expect the CVE cadence to keep tracking the areas the rewrite touched — auth escaping, IMAP parsing limits and the variable expansion introduced in 2.4 — rather than long-settled code. The experimental IMAP4rev2 and mail_utf8 flags are the obvious candidates to graduate once the security churn slows, though nothing in these entries sets a date.
