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.

What is Netcore Cloud?

Netcore's feed remains a demand-generation channel; ten entries, zero product releases.

Nothing in this window is a product release. The feed publishes comparison pages, vertical funnel diagnostics and case studies, in clusters — four posts inside two hours on August 14, two more in the following days. Netcore appears in its own platform rankings, which is the point of the format. Engineering cadence and product direction cannot be read from this source at all.

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.

N5.0

Netcore's feed remains a demand-generation channel; ten entries, zero product releases.

◆ Current state

Nothing in this window is a product release. The feed publishes comparison pages, vertical funnel diagnostics and case studies, in clusters — four posts inside two hours on August 14, two more in the following days. Netcore appears in its own platform rankings, which is the point of the format. Engineering cadence and product direction cannot be read from this source at all.

◆ Where it's heading

The publishing operation is industrialised and aimed at buyers already comparing vendors: category-definition pages, head-to-head buyer's guides, and vertical breakdowns for real estate, hospitality, automotive and ecommerce, most using India-specific funnel data as the credibility hook. The one structural shift visible is a move from pure listicles toward customer-outcome stories, with the media-house newsletter case study framing an existing capability as new revenue rather than new function. Any velocity signal on this product reflects blog output, not shipping.

◆ Prediction

Expect the same weekly cluster of comparison and vertical-funnel posts, with Black Friday framing increasing through the autumn — the pre-BFCM email deliverability post is the first of that seasonal run.
