Restart dovecot after package replacement even when `policy-rc.d` blocks
package-triggered restarts, avoid reinstalling already-correct packages.
Adds proper version separation for dovecot packages:
- Split DOVECOT_VERSION into DOVECOT_ARCHIVE_VERSION (for URLs/filenames)
and DOVECOT_PACKAGE_VERSION (epoch-prefixed for dpkg matching).
- Update _download_dovecot_package() to return (path, changed) tuple
so install() can track whether packages triggered restart intent.
- Use self.need_restart |= changed consistently throughout deployer.
- Move self.need_restart = True inside `if debs:` block -- previously
the apt pin file write unconditionally forced a restart every deploy.
- Comment on dpkg retry pattern (first dpkg may fail on missing deps,
apt-get --fix-broken resolves, then dpkg retries).

fixup
Ensure the preferences.d snippet that pins dovecot packages to block
Debian dist-upgrades is owned by root:root and has 644 permissions.
Files in this directory are generally expected to be world readable to ensure unprivileged operations such as apt-get in simulation mode. Having them not world readable breaks such usages.
As our .deb packages use Debian's version naming scheme, deploy an apt
preferences file that sets Pin-Priority: -1 for all dovecot-* packages
for every version of dovecot-* from every origin.

Relay should not stop validating TLS certificates of other relays
just because it has a self-signed or externally managed certificate.
Externally managed certificate is likely to even be valid.
Since change 635ac7 we try to install Dovecot, even if it is already
running, which fails Dovecot upgrades fail when the installed version
differs from the target because dovecot-imapd/lmtpd dependencies
on dovecot-core: packages are installed one at a time via apt.deb(),
i.e. `dpkg -i`, and dpkg cannot satisfy them dependencies:
```
dpkg: dependency problems prevent configuration of dovecot-imapd:
dovecot-imapd depends on dovecot-core (= 1:2.3.21+dfsg1-3); however:
Version of dovecot-core on system is 1:2.3.21.1+dfsg1-1~bpo12+1.
```
Split _install_dovecot_package into _download_dovecot_package (download
only, return path) and a single server.shell call that passes all .deb
files to dpkg -i together. Uses the same 3-step pattern as pyinfra's
apt.deb: tolerant first dpkg -i, apt-get --fix-broken, then final
dpkg -i to fail if there are still errors.
Prevent services from auto-starting during package installation by
installing a policy-rc.d that exits 101. This avoids dovecot startup
failures when no TLS cert exists yet (e.g. acmetool failed on first run).
Picked out of 62fe113b from hpk/lxcdeploy branch.
The old code did not install updates when the service was running; check
installed version instead of systemd status. Also, rewrite install logic
to extract dovecot version and hashes as module-level constants.
Use blocked_service_startup from lxcdeploy branch as it solves our
problem here too.
Disables IP verification by upgrading filtermail to v0.6,
changelog: <https://github.com/chatmail/filtermail/releases/tag/v0.6.0>
Messages using domain-literal addresses no longer require
to match the origin SMTP connection IP anymore.
This allows for example a relay using IPv4 email addresses
to send messages to other relays over IPv6.
This is not considering a breaking change as IP-address-only
relays are not considered a stable feature.

Similar data is already generated by fsreport
available for the relay operator
and metrics for prometheus are generated by mtail.
Closes <https://github.com/chatmail/relay/issues/431>
Upgrade to filtermail v0.5, which has a built-in DKIM verifier
and disable OpenDKIM on reinject_incoming.

Adds a new tls_external_cert_and_key config option for chatmail servers
that manage their own TLS certificates (e.g. via an external ACME client
or a load balancer).
A systemd path unit (tls-cert-reload.path) watches the certificate file
via inotify and automatically reloads dovecot and nginx when it changes.
Postfix reads certs per TLS handshake so needs no reload.
Also extracts openssl_selfsigned_args() so cert generation parameters
are shared between SelfSignedTlsDeployer and the e2e test.
* cleanup: remove CFFI deltachat bindings usage, and consolidate test support with rpc-bindings
major simplification: all chatmail fixtures used in the test are now created inside the cmdeploy plugin,
and do not inherit anything from other fixture machineries, let alone the legacy deltachat CFFI ones.
also fix that pytest report headers show correct chatmail domains under test
- chatmaild:
- basedeploy.py: Add has_systemd() guard. During Docker image builds
there's no running systemd, so deployers that query SystemdEnabled
facts would crash; this change might also be helpful for non-systemd
platforms.
- cmdeploy:
- cmdeploy.py:
- when deploying to @docker, auto-set CHATMAIL_NOPORTCHECK and
CHATMAIL_NOSYSCTL since neither makes sense inside a container
- --config default now reads CHATMAIL_INI env var, so Docker
entrypoints can point to a mounted ini without CLI flags.
- deployers.py:
- skip port check / CHATMAIL_NOPORTCHECK
- skip echobot systemd cleanup w/ has_systemd
- dovecot/deployer.py:
- Guard sysctl writes behind CHATMAIL_NOSYSCTL
- invert dovecot install check so it works without systemd
- sshexec.py: Add __call__ to LocalExec so cmdeploy status works with
@local target. Without it, cmdeploy status tried to call the
executor directly and got TypeError.
Consolidated from j4n/docker branch commits (selection):
- 8953fde feat(cmdeploy): read CHATMAIL_INI env var for default --config path
- 81d7782 fix(cmdeploy): add __call__ to LocalExec so status works with @local
- 8bba78e docker: disable port check if docker is running. fix#694
- 865b514 docker: replace config flags with env vars, drop docker param (instead of f26cb08)

This elimitates the problem of acmetool failing
to start when nginx is installed already and uses port 80.
This also makes nginx redirect HTTP requests to HTTPS
for setups that don't have acmetool.
