Dovecot vs SimpleTexting
A side-by-side editorial comparison of Dovecot and SimpleTexting — release velocity, themes, recent moves, and the top alternatives to consider.
Dovecot vs SimpleTexting: 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 SimpleTexting?
SimpleTexting's feed is SMS-marketing research and listicles, with no product releases in view.
The crawled feed for SimpleTexting is a content-marketing blog, not a changelog: comparison listicles, consumer survey reports, and vertical how-to guides for SMS marketing. The visible window carries no release notes, so the product's actual capability surface is not observable here. The one product-adjacent post, a website sign-up widget, sits outside the recent window.

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.
SimpleTexting
2.5COMMS
SimpleTexting's feed is SMS-marketing research and listicles, with no product releases in view.
◆ Current state
The crawled feed for SimpleTexting is a content-marketing blog, not a changelog: comparison listicles, consumer survey reports, and vertical how-to guides for SMS marketing. The visible window carries no release notes, so the product's actual capability surface is not observable here. The one product-adjacent post, a website sign-up widget, sits outside the recent window.
◆ Where it's heading
The publishing pattern leans on original survey data as a positioning asset, with reports on consumer texting behavior, generational messaging preferences, and unsubscribe drivers. Cadence is slow and irregular, with a long gap between March and August, and the newest post is a comparison roundup that ranks the category including SimpleTexting itself. Read as marketing strategy, the emphasis is category authority rather than product news.
◆ Prediction
Expect more survey-backed reports and seasonal SMS guides on the same slow cadence. Product-level changes will remain invisible unless the crawl source is pointed at a release-notes page.
