Overview

Every management and configuration object Stalwart exposes over JMAP is documented here. Each page covers the object’s fields, the JMAP methods it supports (with curl examples), the equivalent stalwart-cli commands, and where to find the object in the WebUI.

All objects below are available via the urn:stalwart:jmap capability. Their JMAP type names are prefixed with x: on the wire (for example x:Domain); this prefix is omitted in the CLI.

For telemetry data and permission identifiers referenced from this documentation, see the Events, Metrics, and Permissions pages.
