- install.sh: default repo stalwartlabs/mail-server -> stalwartlabs/stalwart
(renamed), and select the exact /stalwart-<target>.tar.gz asset excluding the
foundationdb build (head -n1 could grab the wrong one).
- config.toml: $env{...} -> %{env:...}% (correct Stalwart macro syntax).
KNOWN ISSUE: Stalwart v0.16 removed TOML config (single config.json datastore +
everything else in the DB via CLI/UI), so this config.toml does not load on
0.16.8 ("Failed to parse data store settings"). Needs either a pinned pre-0.16
version or a migration to the v0.16 config model. Binary is installed; the
service is stopped pending that decision.

# Install Stalwart mail server as a hardened host systemd service on the AX41.
|
|
# Run AFTER bootstrap.sh (and ideally after k3s registration, so cert-sync can
|
|
# immediately pull the real cert). Idempotent — safe to re-run to upgrade.

#
|
|
# sudo ./install.sh

#
|

# What it does: creates the stalwart user + /opt/stalwart layout, downloads a
|
|
# pinned Stalwart binary, installs config.toml + the secrets EnvironmentFile,
|
|
# drops a self-signed bootstrap cert (replaced later by cert-sync), and installs
|
|
# the systemd units (mail service + cert-sync service/timer).
