After restarting pdns/pdns-recursor, wait up to 10 s for the recursor
to actually answer a query before proceeding. Likewise, after
configure_dns(), poll from inside the relay container until the
configured DNS IP responds.
On --destroy-all, unset the incusbr0 dns.mode and raw.dnsmasq network
options so the next lxc-start starts from a clean bridge state.
DNSConfigurationError (caught in main()) is raised on timeout so the
CLI prints a clean error instead of failing later with a cryptic message.
Add cmdeploy "lxc-test" command to run cmdeploy against local containers,
with supplementary lxc-start, lxc-stop and lxc-status subcommands.
See doc/source/lxc.rst for full documentation including prerequisites,
DNS setup, TLS handling, DNS-free testing, and known limitations.
Apart from adding lxc-specific docs, tests, and implementation files in the cmdeploy/lxc directory,
this PR adds the --ssh-config option to cmdeploy run/dns/status/test commands and pyinfra invocations,
and also to sshexec (Execnet) handling. This allows for the host to need no DNS entries for a relay,
and route all resolution through ssh-config. This is used by the "lxc-test" command, which performs
a completely local setup -- again, see docs for more details.
While working on DNS/SSH things i also unified all zone-file handling
to use actual BIND format as it is easy enough to parse back.
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.
feat: support self-signed TLS via underscore domain convention
Domains starting with "_" (e.g. _chat.example.org) automatically use
self-signed TLS certificates instead of ACME/Let's Encrypt. The TLS
mode is derived from the domain name — no separate config option needed.
Internally, when config.tls_cert_mode is "self" (underscore domain):
- Generate self-signed certificates via openssl
- Set Postfix smtp_tls_security_level to "encrypt" (opportunistic TLS)
- Add smtp_tls_policy_map entry for underscore domains
- Skip ACME, MTA-STS and www CNAME checks in `cmdeploy dns`
- Serve /new via GET (not redirect to dcaccount:) with rate-limiting
(nginx limit_req, 2r/s burst=5)
- Return dclogin: URLs with ic=3 (AcceptInvalidCertificates) from /new
- Render QR codes client-side via JavaScript and qrcode-svg
- Use config.tls_cert_path/tls_key_path in Postfix, Dovecot and nginx
templates instead of hardcoded ACME paths
