Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
A side-by-side editorial comparison of Dovecot and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Salesmsg now runs the entire sales-to-NPS loop in one thread — outbound, AI reply, booking, survey, and routing.
Salesmsg has expanded well past SMS messaging into a full-stack sales communication platform. AI agents handle text and voice, execute actions (send SMS, log notes, tag callers, escalate with context), and now route contacts based on NPS scores. The recent addition of native surveys closes a loop that previously required a separate CX tool.

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.
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 has expanded well past SMS messaging into a full-stack sales communication platform. AI agents handle text and voice, execute actions (send SMS, log notes, tag callers, escalate with context), and now route contacts based on NPS scores. The recent addition of native surveys closes a loop that previously required a separate CX tool.
Every release reduces a manual touchpoint. AI agents now handle opt-outs, book meetings from warm replies, write handoff summaries, log post-call notes, and route contacts by survey score — all without rep intervention. The trajectory is toward a fully autonomous outreach-to-feedback cycle where humans review outcomes rather than manage steps.
The next move will likely be survey-score-triggered AI agent sequences — automatically enrolling detractors in win-back flows and promoters in referral asks based on NPS results. The routing logic already exists; wiring it to agent automation is the obvious completion.
