Salesmsg vs Rspamd: at a glance
What is Salesmsg?
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
What is Rspamd?
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.

Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
◆ Current state
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
◆ Where it's heading
With AI now able to send messages, Salesmsg is adding the brakes: an organization-wide stop switch and weekly reports on what its AI agents did. Calling features keep catching up with texting, with queue callbacks and recording rules.
◆ Prediction
Expect more controls over what Sherpa and AI agents may send, such as per-agent limits or approval rules, alongside further HubSpot call-data sync.
Rspamd
5.0COMMS
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
◆ Current state
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
◆ Where it's heading
Since 4.1, every release has hardened parsers and closed memory-safety and trust gaps; 4.3 applies the same pass to the authentication standards themselves (SPF, DKIM, DMARC, ARC) and to content extraction. Operators should expect scores and fuzzy hashes to shift after upgrading, because the project now favours spec-correct results over backward-compatible ones.
◆ Prediction
A 4.3.x point release fixing regressions from these behaviour changes is the likely next step, as 4.2.1 followed 4.2.0 within two weeks.
