Roundcube vs Salesmsg
A side-by-side editorial comparison of Roundcube and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
Roundcube vs Salesmsg: at a glance
What is Roundcube?
After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.
What is Salesmsg?
Salesmsg is turning a texting inbox into an AI agent that also answers the phone.
Salesmsg ships weekly against three tracks: AI agents that hold conversations and take actions, a voice layer that now includes queues, IVR, and simultaneous inbound calls, and deep write-access into HubSpot and Salesforce. Agent work has moved past prompt-writing — agents are built by chatting, tested live before launch, run off live data sources, and book meetings directly into a CRM over SMS. The July release adds per-workflow credit accounting, which is the first sign the company is treating agent spend as something customers need to audit.

Roundcube

After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
◆ Current state
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.
◆ Where it's heading
The arc is a long-lived webmail codebase paying down structural risk. 1.7.0's headline changes are defensive rather than user-facing: a mandatory public_html/ entry point so installations aren't exposed by default, improved OAuth2/OIDC support including discovery and logout, removed code bloat and automated code style and quality checks. Everything since has been paired security releases across both lines, several of them reporting classes of bug — sanitizer bypasses, injection through plugin queries — that the 1.7 hardening work is aimed at. Expect the security cadence to stay high while the 1.6 LTS remains supported.
◆ Prediction
Expect continued same-day paired security releases on 1.6 and 1.7, with 1.7.x accruing incremental OIDC and sanitizer hardening before any 1.8 work becomes visible.
Salesmsg
6.3COMMS
Salesmsg is turning a texting inbox into an AI agent that also answers the phone.
◆ Current state
Salesmsg ships weekly against three tracks: AI agents that hold conversations and take actions, a voice layer that now includes queues, IVR, and simultaneous inbound calls, and deep write-access into HubSpot and Salesforce. Agent work has moved past prompt-writing — agents are built by chatting, tested live before launch, run off live data sources, and book meetings directly into a CRM over SMS. The July release adds per-workflow credit accounting, which is the first sign the company is treating agent spend as something customers need to audit.
◆ Where it's heading
The product is consolidating from a set of channels into a single automated front desk: text, call, route, book, and now collect the review afterward. Each CRM release moves work from the human to the agent — enrollment from Salesforce Flows, reschedules handled over text, call outcomes logged without a manual save. The newest release pushes past conversations entirely into reputation, which is the standard expansion path for SMB messaging platforms and puts Salesmsg on the same ground as the review-and-messaging suites rather than pure SMS tools.
◆ Prediction
Expect the review product to be wired into agents and workflows next — automatic review requests triggered by a closed conversation or a completed booking — and further credit and permission controls as agent usage grows. The Salesforce and HubSpot tracks look set to continue on a quarterly bundle cadence.
