Dovecot vs Elastic Email
A side-by-side editorial comparison of Dovecot and Elastic Email — release velocity, themes, recent moves, and the top alternatives to consider.
Dovecot vs Elastic Email: at a glance
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 Elastic Email?
A deliverability vendor ships DMARCRadar and lets case studies do the rest of the talking.
The feed is a marketing blog with one product launch in it. DMARCRadar, a DMARC monitoring tool, is the only release in this window; everything around it is customer case studies, an explainer on what an email service provider does, an agency-scaling piece, and now a comparison post against MailerSend. The company is competing on price and deliverability rather than on feature surface.

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.
Elastic Email
6.3COMMS
A deliverability vendor ships DMARCRadar and lets case studies do the rest of the talking.
◆ Current state
The feed is a marketing blog with one product launch in it. DMARCRadar, a DMARC monitoring tool, is the only release in this window; everything around it is customer case studies, an explainer on what an email service provider does, an agency-scaling piece, and now a comparison post against MailerSend. The company is competing on price and deliverability rather than on feature surface.
◆ Where it's heading
The positioning is consistent: own the authentication and deliverability layer, then argue cost against developer-first rivals. DMARCRadar extends the platform from sending into monitoring whether mail is trusted at all, while the MailerSend comparison shows where the commercial pressure is coming from. The case studies, including a six-year customer, are retention proof aimed at the same small-team buyer the pricing argument targets.
◆ Prediction
Expect further comparison posts against transactional-email rivals and more build-out around DMARCRadar's reporting. Nothing in these entries points to a change in the core sending platform.
