Rocket.Chat vs Dovecot: at a glance
What is Rocket.Chat?
Rocket.Chat is spending 8.x on the auth and access-control layer regulated buyers ask about.
Rocket.Chat ships a public release-candidate train where the .rc.0 of each minor carries every feature and the RCs after it are dependency bumps. The 8.7 line leads with a server-side OAuth flow that adds PKCE, CSRF and state validation, and forces 2FA even on Google, GitHub and GitLab logins. The 8.6 line before it added Virtru as an external attribute store for ABAC decisions, LibreTranslate as a self-hostable auto-translation provider, and the backend for a unified presence engine.
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.
Rocket.Chat vs Dovecot: editorial side-by-side
Rocket.Chat
6.3COMMS
Rocket.Chat is spending 8.x on the auth and access-control layer regulated buyers ask about.
◆ Current state
Rocket.Chat ships a public release-candidate train where the .rc.0 of each minor carries every feature and the RCs after it are dependency bumps. The 8.7 line leads with a server-side OAuth flow that adds PKCE, CSRF and state validation, and forces 2FA even on Google, GitHub and GitLab logins. The 8.6 line before it added Virtru as an external attribute store for ABAC decisions, LibreTranslate as a self-hostable auto-translation provider, and the backend for a unified presence engine.
◆ Where it's heading
The feature mix points squarely at self-hosted and compliance-driven deployments rather than at chat features. Auth hardening, attribute-based room access delegated to an external policy store, and translation that never leaves the network are all answers to procurement questions, not user requests. Federation and device-session management are getting steady repair work alongside.
◆ Prediction
Expect 8.7 to reach GA with the modern OAuth flow still behind the Accounts_OAuth_Use_Modern_Flow setting, and the presence-engine foundation from 8.6 to surface as user-visible status controls in a later minor.
Dovecot
0.0COMMS
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.
