📋 Script Details
Stalwart is an all-in-one mail and collaboration server in Rust: SMTP, IMAP, POP3, JMAP, CalDAV, CardDAV and WebDAV plus spam filtering and DKIM/SPF/DMARC, from a single binary with an embedded RocksDB store — no external database for a default install.
- Stack:
prebuildmode (stalwart-<arch>-unknown-linux-gnu.tar.gz),stalwart --config=/opt/stalwart_data/etc/config.json. - Self-bootstrapping: the binary creates
config.jsonon first start and prints a temporary admin password to the journal — same behaviour the upstream Docker image relies on with an empty/etc/stalwartvolume. Admin UI at:8080/admin.journalctl -u stalwart | grep -A8 'bootstrap mode'
- Persistence:
/opt/stalwart_data/{etc,data,logs}, plusstalwart.envforSTALWART_HOSTNAME/STALWART_PUBLIC_URL. - v0.16 note: configuration is no longer TOML — only a small
config.jsondescribing the datastore lives on disk, everything else is a JMAP object in the DB, managed through the web UI orstalwart-cli.

The Stalwart script is ready for testing:
Default credentials:
Username: admin
On first start Stalwart runs in bootstrap mode and generates a temporary admin password. Read it with: journalctl -u stalwart | grep -A8 'bootstrap mode'. Then finish setup at http://:8080/admin.
Running a mail server that is reachable from the internet needs correct DNS (MX, SPF, DKIM, DMARC, rDNS/PTR) and a valid TLS certificate. Set STALWART_HOSTNAME and STALWART_PUBLIC_URL in /opt/stalwart_data/etc/stalwart.env, then restart the service.
Configuration and mail data live in /opt/stalwart_data (etc, data, logs), outside the app directory, so they survive updates. Include this directory in your backups.
The default datastore is embedded RocksDB - no external database needed. PostgreSQL, MySQL, SQLite, S3, Redis and NATS backends can be configured later through the admin UI.
Note: This is not in the official repo yet—it's just a dev version! After merging into ProxmoxVE, it will need to be recreated.
