Dovecot vs Salesmsg: at a glance
What is Dovecot?
Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
What is Salesmsg?
Salesmsg Reviews can now trigger follow-ups automatically based on a customer's latest rating.
Salesmsg upgraded Reviews: follow-ups can fire automatically based on a customer's most recent rating, reviewers can be messaged in bulk or answered directly from review analytics, and results can be exported. It follows an official MCP server listed with Claude and ChatGPT, call tracking and AI call scorecards, and recurring NPS surveys that enrol contacts in automations.

Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
◆ Current state
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
◆ Where it's heading
Two things are being worked at once. Security is the visible half, and the volume is striking — resource-exhaustion and parser issues in IMAP THREAD, LIST and ID, a CRIME-style compression side channel, an authentication bypass through XCLIENT forwarding. The quieter half is that fixes are increasingly gated behind version declarations: the THREAD fix needs a new index format enabled only by raising dovecot_storage_version. That mechanism, introduced with 2.4.0, is now doing real work, letting operators take format changes on their own schedule.
◆ Prediction
Experimental flags for mail UTF-8 and IMAP4rev2 have carried unchanged through every 2.4 release so far; the next branch-defining move is one of those graduating to default rather than another security round.
Salesmsg
5.0COMMS
Salesmsg Reviews can now trigger follow-ups automatically based on a customer's latest rating.
◆ Current state
Salesmsg upgraded Reviews: follow-ups can fire automatically based on a customer's most recent rating, reviewers can be messaged in bulk or answered directly from review analytics, and results can be exported. It follows an official MCP server listed with Claude and ChatGPT, call tracking and AI call scorecards, and recurring NPS surveys that enrol contacts in automations.
◆ Where it's heading
Salesmsg is connecting feedback (surveys, NPS, reviews) to its texting and calling automations, so a customer's score decides what happens next. Alongside that, AI agents for calls and texts and the MCP server extend who, or what, can act on those conversations.
◆ Prediction
Expect review and survey scores to feed the AI texting and calling agents directly, and more CRM sync for review data.
