Fixes an issue with the Getmail service, view PR thread for additional details.
- Log an error when the expected service state directory doesn't exist.
- The location `/var/lib/getmail/` doesn't seem like it should have been introduced. Drop it in favor of `/tmp/docker-mailserver/getmail`. It appears to be for storing remote mail that was retrieved if not configured to send to Dovecot like our docs advise. This location was never valid anyway (_as referenced issue covers_).
Custom parameters must be referenced to be retained when `postconf -n` is run. If those parameters are referenced by `postfix-master.cf` this needs to update `master.cf` before updating `main.cf`.
* docs: Better document DMS volumes
* docs: Remove any mention of `ONE_DIR` ENV
* chore: Remove `ONE_DIR` ENV from scripts
Only `ONE_DIR=0` has any effect. As the actual feature is now dependent upon the `/var/mail-state` location existing.
It is advised not mounting anything there instead if wanting to avoid runtime state consolidation.
* docs: Adjust link ref convention
This is more search friendly / organized to find references to all DMS volumes.
* lint: Ensure final newline is present
VSCode by default excludes this if the last line rendered is removed (rendered as a separate blank line).
A separate setting can enforce adding the final newline upon save regardless.
* setup-stack: fix error when RSPAMD_DMS_DKIM_D is not set
prevent messages like this
chown: cannot access '': No such file or directory
when RSPAMD_DMS_DKIM_D has no value
* Update target/scripts/startup/setup-stack.sh

* chore: Detect missing final newline in configs read
These lines will be not be processed by `read`, emit a warning to raise awareness.
* fix: Ensure parsed config has final newline appended (when possible)
This functionality was handled in `accounts.sh` via a similar sed command (that the linked references also offer).
`printf` is better for this, no shellcheck comment required either.
We additionally don't attempt to modify files that are read-only.
* fix: Ensure parsed configs have CRLF to LF corrected (where possible)
Likewise, this runtime fix was only covering two config files. It now applies to all callers of this method.
* fix: Sanitize `postfix-master.cf` via helper
This feature should have been using the helper to avoid user error from their config updates accidentally introducing subtle breakage implicitly (due to CRLF or missing final newline).
* tests: Add test cases for new helpers
* tests: `rm` is redundant when using `BATS_TEST_TMPDIR`
This temporary directory is created and removed implicitly. Even after a test failure.
* chore: Remove old `postfix-virtual.cf` migration logic
This was introduced in 2018, there should be no one needing to rely on this anymore?
* tests: Remove comment on sed failure concern
* chore: Add entry to `CHANGELOG.md`
* Apply suggestions from code review

The UID / GID shifted during a new release. Until DKIM handling is refactored in a new major release, this fix ensures the content maintains the expected `_rspamd` ownership.
This is a more explicit reminder for any future contributors that get thrown off by the usage of `sed` here and may be inclined to change it.
Add a link to reference a comment where it's already been explored what the alternative `sed` invocations available are.
* feat: add support for MTA-STS for outgoing mails
* Hook-up mta-sts-daemon into basic process handling test
* fix: Call python script directly
The python3 shebang will run it, which will now meet the expectations of the process testing via pgrep. fail2ban has the same approach.

* chore: Disable `smtputf8` support in config
This was always configured disabled at runtime, better to just set explicitly in `main.cf` unless config diverges when Dovecot is enabled to opt-out of this feature.
* added check for Rspamd DKIM on startup
The newly added function `__rspamd__check_dkim_permissions` performs a
check on DKIM private key files. This is useful to prevent issues
like #3621 in the future. The function is deliberately kept simple and
may not catch every single misconfiguration in terms of permissions and
ownership, but it should be quite accurate.
Please note that the Rspamd setup does NOT change at all, and the checks
will not abort the setup in case they fail. A simple warning is emmited.
* add more documentation to Rspamd functions
* Apply suggestions from code review
* improve `__do_as_rspamd_user`
* rework check similar to review suggestion

* update K8s deployment
Because `allowPrivilegeEscalation` controls SUID/SGID, we require it
when postdrop is invoked.
* correct permissions for maildrop/public
The reason our permissions previously worked out as that in setups where
SUID/SGID worked, the binaries used to place files in these directories
already have SGID set; the current set of permissions makes less sense
(as explained in this comment:
https://github.com/docker-mailserver/docker-mailserver/issues/3619#issuecomment-1793816412)
Since the binaries used to place files inside these directories alredy
have SUID/SGID set, we do not require these bits (or the sticky bit) to
be set on the directories.

* outsource Rspamd ENVs into explicit helper
This will allow us to uniformly source the helper and get the values
from everywhere consistently. This is more than desirable since we will
be using these values not only for the Rspamd setup, but also for DKIM
management and during change-detection.
* integrate Rspamd into changedetection
We outsource one more function to reside in the helper script for Rspamd
so that we can call this function from the Rspamd setup and from the
changedetection functionality too.
* realize deprecation of old commands file for Rspamd
THIS IS A BREAKING CHANGE!
This change realizes the log message: "Using old file location now
(deprecated) - this will prevent startup in v13.0.0" Startup will now
fail.
* added '--force' option to Rspamd DKIM script
* use new helper to get ENVs for Rspamd in DKIM script
* remove the need for linking directories
This was unnecessary, as explained in
https://github.com/docker-mailserver/docker-mailserver/pull/3597#discussion_r1369413599
* Apply suggestions from code review

Instead of using `etc/rspamd/override.d/dkim_signing.conf`, we will now
be using `/tmp/docker-mailserver/rspamd/override.d/dkim_signing.conf`.
The new location is persisted (and linked again during startup) and
hence better suited.
* simplify `_setup_logrotate`
* adjust Rspamd's log file and improve it's management
* add information to docs about Rspamd log
* update log query helper to allow another file location
* bail in case `LOGROTATE_INTERVAL` is invalid

Some deployment scenarios are not compatible with `5000:5000` static vmail user with `/var/mail`. This feature allows adjusting the defaults to a UID / GID that is compatible.

* chore: Drop management of `SASLAUTHD_*` ENV
- `variables-stack.sh` does not need to manage all these extra ENV or store them. They're not used anywhere else.
- `saslauthd.sh` is the only consumer of these ENV which are effectively direct key/value mappings, with some defaults provided / inherited.
Instead of trying to conditionally support key/value pairs when ENV is set, we could instead use `sed` to delete lines with empty values.
* chore: Drop fallbacks + update configs to match docs
- Drop deprecated support:
- `DOVECOT_HOSTS` is an ENV deprecated since v10.
- Fallback for missing URI scheme introduced for Dovecot and SASLAuthd in v10.
- Adding error log message when no LDAP URI scheme is detected for the supported ENV (when set).
- Docs updated for ENV to reflect the mandatory requirement. `mailserver.env` partially synced equivalent sections.
- Provided base LDAP configs (for overriding) likewise updated from `domain.com` to `example.com`.
- LDAP test updated for required `ldap://` URI scheme. Common ENV shared across LDAP configs hoisted out of the Postfix group.
* chore: Remove unset lines in generated `saslauthd.conf`
- Deprecation startup script check is kept for `ENABLE_LDAP=1` but adjusted to emit an error instead. It can be dropped in a future release. Just a precaution for those who mistakenly update (_possibly via automation_) without checking the release notes, an error log is somewhat helpful, although it could alternatively panic?
- Docs updated to remove the `ENABLE_LDAP=1` usage
- ENV docs updated to reference a maintained LDAP image.
- Changelog includes the breaking change, and slight revision to prior release mention of deprecation.
The new function can
1. update/append
2. update/prepend
3. initialize if non-existent
options in `/etc/postfix/main.cf` in a safe and secure manner. When the
container is improperly restarted, the option is not applied twice.

* Fix issue with concatenating $dmarc_milter and $dkim_milter in main.cf
Upon each start the `smtpd_milters` and `non_smtpd_milters` would be extended with the following:
```
smtpd_milters = $dmarc_milter $dkim_milter
non_smtpd_milters = $dkim_milter
```
In my case they became long enough that mail delivery stopped. I think this was because of the extra headers that are added by these steps. (which in turn would cause the mail to be dropped)
* fix sed to work when the variables are there and when they are not.
