* docs: Debugging - Delivery failure from service downtime
Services may be temporarily down, such as when restarted when certificates are updated due to the `check-for-changes.sh` service. This is another known source of intermittent delivery failures.
* chore: Extract out Dovecot Quota test cases into new test file
Test cases are just cut + paste, no logic changed there yet.
* chore: Rename test case descriptions
* chore: Use `setup ...` methods instead of direct calls
* chore: Adjust `_run_in_container_bash` to `_run_in_container`
Plus some additional bug fixes in the disabled test case
* tests(refactor): Revise ENV test cases for max mailbox and message sizes
* tests(refactor): Revise ENV test cases for mailbox and message limits v2
Removes the extra variables and filtering in favour of explicit values instead of matching for comparison.
- Easier at a glance to know what is actually expected.
- Additionally reworks the quota limit checks in other test cases. Using a different formatter for `doveadm` is easier to match the desired value (`Limit`).
* chore: Sync improvement from `tests.bats` master

NOTE: This PR has been merged to avoid additional maintenance burden without losing the improvements. It was not considered complete, but remaining tasks were not documented in the PR.
* scripts: Install rspamd from official repository instead of debian backports on arm64 architecture
* Remove unnecessary deb-src repository for rspamd
* Remove note about ARM64 rspamd version, update CHANGELOG.md

* fix: Source `VERSION` from image ENV
Now CI builds triggered from tagged releases will always have the correct version. No need for manually updating a separate file.
* fix: Query latest GH release tag
Compare to the remote GH release tag published, rather than contents of a `VERSION` file.
`VERSION` file remains in source for now as prior releases still rely on it for an update notification.
* chore: Switch from `yq` to `jaq`
- Can more easily express a string subslice.
- Lighter weight: 9.3M vs 1.7M.
- Drawback, no YAML input/output support.
If `yq` is preferred, the `v` prefix could be removed via BASH easily enough.
* chore: Add entry to `CHANGELOG.md`
* ci: `VERSION` has no relevance to `:edge`
* docs: Update build guide + simplify `make build`

* 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

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.

The subnet must be specified as part of `ipam.configs`.
This was unfortunately slightly incorrect due to a mistake in the official Docker docs being propagated, which has since been fixed upstream.
Refer to the official Compose Spec for more details:
* https://docs.docker.com/compose/compose-file/06-networks/#ipam
* 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.
* chore: Adjust default DKIM size (`open-dkim`) from 4096-bit to 2048-bit
4096-bit is excessive in size for DKIM key. 2048-bit is plenty.
* chore: Additional revisions to `open-dkim` command help output
- The examples use `keysize 2048`, but as that's the new default it makes sense to change that.
- Other help text was also revised.
- Last example for domains did not need to demonstrate the other options. Changed example domains to more appropriate values.
* docs: Revise DKIM docs
Primarily for the change in default key size, but does revise some text to better communicate to the user.
- While the referenced RFC advises 512-bit to 2048-bit key size, we now explicitly discourage `512-bit` as it's not secure. `1024-bit` is still likely safe for most, but `2048-bit` is a good default for those not rotating their keys.
- Adjusted the domains example to match the new `setup config dkim domain` domains example.
- Tip for changing default key size changed to "info" with added clarity of lowering security or increasing it (excessively).
- Rspamd section is minor formatting changes, with the exception of clarifying the "main domain" for the mail accounts is assumed as the DMS FQDN with any subdomain (like `mail.`) stripped away. This is not great, but a legacy issue that needs to be addressed in future.
- `docs-rspamd-override-d` ref removed, and usage replaced with equivalent ref `docs-rspamd-config-dropin`, while `docs-rspamd-config-declarative` ref was not in use and also removed.
- Revised the `<selector>.txt` DNS formatting info section to better communicate with the reader. Additionally it had mixed usage of default `mail` and custom `dkim-rsa` selectors (_file content and output_).
* docs: Sync DKIM commands help messages and update DKIM docs for LDAP
- Adopt the help options format style from the `rspamd-dkim` into `open-dkim` command. And convert `./setup.sh` to `setup`. `selector` option has been implemented. for a while now.
- Update `rspamd-dkim` examples help output to align with `open-dkim` command examples.
- Give both DKIM command tools a consistent description. The two tools differ in support for the `domain` option (_implicit domain sourcing for default account provisioner, and support for multiple domains as input_).
- DKIM docs for LDAP domain support revised to better communicate when explicit domain config is necessary.
* tests: Adjust test-cases for `setup config dkim` change
`rspamd_dkim.bats`:
- Update assert for command help output.
- Don't bother creating a DKIM key at 512-bit size.
`setup_cli.bats`:
- Update assert for command help output of the `setup config dkim` (OpenDKIM) command.
* docs: Update DKIM section for large keys to newer RFC
The linked discussion from 2021 does mention this updated RFC over the original. That removes outdated advice about `512-bit` key length support.
The discussion link is still kept to reference a comment for the reader to better understand the security strength of 2048-bit RSA keys and why larger keys are not worthwhile, especially for DKIM.
* docs: Extract out common DKIM generation command from content tabs
Should be fine to be DRY here, not specific to `open-dkim` or `rspamd` generation/support. Previously rspamd lacked support of an equivalent command in DMS.
* docs: DKIM refactoring
- Shifted out the info admonition on key size advice out of the content tabs as it's now generic information.
- Indented the 4096-bit warning into this, which is less of a concern as the default for our DKIM generation tools is consistently 2048-bit now.
- Reworked the LDAP and Rspamd multi-domain advice. To avoid causing a bad diff, these sections haven't been moved/merged yet.
* docs: Revise DKIM docs
Advice for managing domains individually with LDAP and Rspamd extracted out of the content tabs. Default domain behaviour explained with extra info about OpenDKIM + FILE provisioner sourcing extra domains implicitly.
Adding `internet.nl` mail tester, this testing services gives users in-depth analysis of their mail server, connectivity, DKIM/SPF/DMARC records and DNS.
For added clarity, a user requested we document the example config snippets instead of only linking external references to them. Revised section and adjusted to presenting via the content tabs feature.
docs: Add compatibility section to debugging page
ci: Adjust bug report template
Reduce some text + compress the preliminary checks down to single check item.
* adjust learning of ham
See #3333
When moving a mail from the Junk folder to the Trash folder, the mail
previously classified as ham due to the wildcard match of `*`. Because
the syntax does not allow for negation, we can only change the behavior
in a way that mails are learned as ham when they are moved into `INBOX`
from `Junk`. This is reasonable though.
* adjust tests accordingly
* adjust docs accordingly
