The private direction of the mode switch is exercised end to end. The
public one has only ever run against a throwaway .test domain, where Let's
Encrypt rejects the contact address before the provider is created — so
everything past that call is reasoned rather than observed.
The plan shape IS confirmed up to that point: contact is a set, matchOn is
the directory URL, and a domain cannot reference automatic certificate
management without an acmeProviderId. What is unproven is the link holding
once the provider actually exists.
Saying so in the file beats leaving it in a chat log nobody reads.

Switching between private and public wrote the setting, reconfigured the
server and then asked the user to run `libreportal app install stalwart`
to make the ports actually change. That left a window where the WebUI
reported public while port 25 was still closed — or worse, reported
private while 25 was still open and listening. A mode switch that does not
move the ports is not a mode switch.
The tool now runs the install itself. Safe from here: tools are dispatched
inline rather than as their own task, so this is not a nested task and
cannot deadlock on the task lock, and nothing in Stalwart's install hooks
calls back into the tool. Provisioning inside that install is a no-op
because it skips once config.json exists.
Dropped the separate firewall rebuild — the install reallocates the ports
and rebuilds the rules from the result, so doing it beforehand only worked
from the old allocation and was then immediately redone.
Verified both directions on a real install: private -> public publishes 25,
public -> private removes it, the admin port keeps its existing random
allocation across both (no --reset-network, so bookmarked WebUI links do
not move), mailboxes survive with their original creation timestamps, and
re-selecting the current mode is a no-op.

A mail server is two quite different products wearing one name, and until
now LibrePortal only offered the hard one. Installing Stalwart meant being
handed a wall of DNS records, a red error about port 25 and a warning about
reverse DNS — all of it correct, none of it fixable by the installer, and
most of it irrelevant to someone who wanted mailboxes and a shared calendar
on their own network.
CFG_STALWART_MODE now names which one you are running:
private mailboxes, IMAP, CalDAV and CardDAV on your own network. Port 25
is not published at all; the client ports stay bound to the host
but are never opened through the firewall. No MX, no PTR, no
deliverability. Nothing to publish, so nothing is printed.
public the internet mail server, as before.
auto public if Traefik is installed, private if not, resolved at
install and written back so it reads as a real answer afterwards.
DKIM keys are generated in both modes even though private has no use for
them today — that is what makes switching later a setting change rather
than a key ceremony. The WebUI gets a "Mail Exposure" tool that flips the
setting both ways and reconfigures the server, plus a "Show DNS Records"
tool that prints the live zone including current DKIM keys.
Two things this had to get right, both found by testing rather than
reading. Port access lives in the shell as CFG_<APP>_PORT_n, not just in
the config file, and the compose file is built from the parsed shell
values — editing only the file left the config claiming port 25 was
disabled while the container published it anyway. And going public needs
an AcmeProvider to exist before a domain can reference one, so the switch
creates it; note that doing so registers an account with Let's Encrypt.
Verified through real installs: auto resolves to private with no Traefik,
port 25 is genuinely unpublished and absent from the compose file, the
client ports are skipped by the firewall as host-bound, and the tool
round-trips private -> public -> private with the config landing back
exactly where it started.
