Mailu vs Salesmsg: at a glance
What is Mailu?
Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
Mailu's 2024.06 branch ships pinned releases, each tied to a single issue. October brought resolver fixes for the DNSSEC KSK rollover and SERVFAIL healthchecks, Roundcube 1.6.20, then PHP2Shell CVE mitigations in webmail followed by the patched PHP runtime. 2024.06.68 on 8 November carries the same PHP2Shell mitigation note again.
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.

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
◆ Current state
Mailu's 2024.06 branch ships pinned releases, each tied to a single issue. October brought resolver fixes for the DNSSEC KSK rollover and SERVFAIL healthchecks, Roundcube 1.6.20, then PHP2Shell CVE mitigations in webmail followed by the patched PHP runtime. 2024.06.68 on 8 November carries the same PHP2Shell mitigation note again.
◆ Where it's heading
The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.
◆ Prediction
The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.
Salesmsg
6.3COMMS
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.
