What is Stalwart?

Stalwart is shipping email's next-generation auth stack while the specs are still in draft.

Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

What is Twist?

A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.

This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.

Stalwart vs Twist: editorial side-by-side

S5.0

Stalwart is shipping email's next-generation auth stack while the specs are still in draft.

◆ Current state

Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

◆ Where it's heading

The project is building toward being the reference implementation of the modern mail stack — JMAP first, with the classic protocols held at parity rather than left behind. The fix lists have shifted in character over these eight releases: less "feature does not work", more "spec detail is wrong", which is what a codebase looks like as it converges on conformance. Security and multi-tenancy fixes keep appearing alongside the protocol work, indicating real deployments are exercising the newer subsystems.

◆ Prediction

The next releases most likely track revisions to the drafts already implemented — DKIM2, JMAP push and the calendar drafts are all still moving — rather than adding another protocol surface. Expect continued JMAP conformance fixes until the test suite stops producing them.

0.0

A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.

◆ Current state

This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.

◆ Where it's heading

The trajectory in the captured window points to operational maintenance rather than category expansion: tightening data validation, fixing edge cases in audit reporting, supporting more telecom-data formats. The earlier Bouygues API connector hinted at a machine-to-machine ambition with the major French carriers, but follow-through (Orange, SFR) is not visible in this window. Public release cadence appears to have gone quiet.

◆ Prediction

Hard to call from the visible entries. If the Orange and SFR API connectors promised in 2024 ever shipped, they would have been the natural next chapter; their absence suggests either delayed delivery or a move to private release notes. Watch for whether public changelog cadence resumes at all.
