refactor: `relay.sh` (#3845)
* chore: `relay.sh` helper - Reference user config paths via variables

* chore: Better document postfix helper `_vhost_collect_postfix_domains()`

The functionality is effectively the same for the two configs for the most part when it comes to parsing out a domain from the target value.

Virtual aliases is more flexible in value, which may not have a domain-part present (manual user edit).

* chore: `check-for-change.sh` - Support VHOST change visibility

- Moves the "handle changes" logic into it's own scoped function, out of the main change detection loop logic.
- This will be benefit a future commit change that will rely on `VHOST_UPDATED=1`.

* chore: `relay.sh` - Minor revisions to minimize diff noise

- Better phrasing of the current logic comments.
- Regex patterns assigned to variables (easier to grok intention)
- Bulk of the logic for generating `/etc/postfix/relayhost_map` wrapped into a separate function with Postfix config setting handled separately.

* refactor: `relay.sh` opt-out logic

- Split the two distinct features that configure `/etc/postfix/relayhost_map` into separate functions (_`MATCH_VALID` var no longer needed for legacy support_).
- Instead of extracting domains from `postfix-accounts.cf` + `postfix-virtual.cf`, this has already been handled at `/etc/postfix/vhost`, sourcing from there is far less complicated.
- Rename loop var `DOMAIN_PART`to `SENDER_DOMAIN` for better context of what it represents when appended to the config file.
- Revised maintenance notes + guidance towards a future refactor of this relayhost feature support.

* docs: `relay.sh` - Additional comment revisions

* feat: `DEFAULT_RELAY_HOST` can now also use relay credentials ENV

- Remove comment regarding `smtp_sasl_password_maps = static:${RELAY_USER}:${RELAY_PASSWORD}`, it could be used but `main.cf` presently has `644` permissions vs the `sasl_passwd` file permissions of `600`, less secure at preventing leaking of secrets (ignoring the ENV exposure itself).
- Move the `main.cf` settings specific to relayhost credentials support / security into to the relevant function scope instead. This also allows for the configuration to be applied by a change detection event without container restart requirement.
- Outer functions for setup and change detection to call have a clearer config dependency guard, as does the `_legacy_support()`.
- These changes now support `DEFAULT_RELAY_HOST` to leverage the relay credentials ENV as well.
- `DATABASE_RELAYHOSTS` is available in scope to the functions called here that reference it.

* docs: Revised ENV docs on relay host config

Better quality guidance on configuring relay hosts.

* chore: Add entry to `CHANGELOG.md`

* fix: `relay.sh` - `grep` regex compatibility with `+` requires `-E`

* chore: `postfix.sh` - `FIRST_FIELD` => More descriptive field name

docs: Remove ENV `ONE_DIR` (#3840)
* 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.

fix: Revert quoting `SA_SPAM_SUBJECT` in `mailserver.env` (#3767)
In Docker Compose `.env` files are parsed properly when values are wrapped with quotes. Trailing white-space is also discarded, like it would be with shell variables.

This is not the case with `docker run` or other CRI like `podman` (_including it's compose equivalent support_). Those will parse the quotes to be included in a literal string value. Trailing white-space is also retained.

Hence a default with a trailing space is not compatible across CRI. This change documents the default with additional context on how to include a trailing white-space with a custom value for the users CRI choice. It additionally clearly communicates the opt-out value for this feature.

tests(refactor): Dovecot quotas (#3068)
* 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

chore: LDAP config improvements (#3522)
* 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`

chore: Adapt `ENABLE_LDAP=1` to `ACCOUNT_PROVISIONER=LDAP` (#3507)
- 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.

feature: provide better rspamd suppport (#3016)
* added options to toggle OpenDKIM & OpenDMARC

rspamd can provide DKIM signing and DMARC checking itself, so users
should be able to disable OpenDKIM & OpenDMARC. The default is left at
1, so users have to to opt-in when the want to disable the features.

* misc small enhancements

* adjusted start of rspamd

The order of starting redis + rspamd was reversed (now correct) and
rspamd now starts with the correct user.

* adjusted rspamd core configuration

The main configuration was revised. This includes AV configuration as
well as worker/proxy/controller configuration used to control the main
rspamd processes.

The configuration is not tested extensively, but well enough that I am
confident to go forward with it until we declare rspamd support as
stable.

* update & improve the documentation

These are some initial tests which test the most basic functionality.

tests(refactor): `mail_lmtp_ip.bats` (#3004)
* chore: Drop ENV `ENABLE_POSTFIX_VIRTUAL_TRANSPORT`

* tests(chore): Remove redundant `dovecot-lmtp` config

None of this is needed. Only relevant change is changing the LMTP service listener for Dovecot and that can be delegated to `user-patches.sh`.

* tests(refactor): Use `user-patches.sh` instead of replacing config file

The only relevant changes in `test/config/dovecot-lmtp` regarding LMTP was:
- `/etc/dovecot/dovecot.conf` (`protocols = imap lmtp`) and `/etc/dovecot/protocols.d/` (`protocols = $protocols lmtp`).
- `conf.d/10-master.conf` only changed the LMTP service listener from a unix socket to TCP on port 24 (_this was the only change required for the test to pass_).

None of those configs are required as:
- `protocols = imap pop3 lmtp` [is the upstream default](https://doc.dovecot.org/settings/core/#core_setting-protocols), no need to add `lmtp`.
- The LMTP service listener is now configured for the test with `user-patches.sh`.

* tests(refactor): `mail_lmtp_ip.bats`

- Converted to new testing conventions and common container helpers.
- `ENABLE_POSTFIX_VIRTUAL_TRANSPORT` was not relevant, dropped.
- Revised test cases, logic remains the same.
- Large custom config used was not documented and doesn't appear to serve any purpose. Simplified by replacing with a single modification with `user-patches.sh`.
- Added some additional comments for context of test and improvements that could be made.

* tests(chore): Adjust comments

The comment from `mail_hostname` provides no valid context, it was likely copied over from `tests.bats` in Oct 2020 by accident.

The email sent is just for testing, nothing relevant to LMTP.

---

Added additional comment for test to reference extra information from.

* tests(chore): Update similar log line matching

Extracts out the match pattern and formatting commands into separate vars (reduces horizontal scrolling), and includes extra docs about what the matched line should be expected to look like.

scripts: rework environment variables setup (#2716)
* outsourcing env variable setup

This commit contains major parts of the work of refactoring the setup
and usage of environment variables. It outsources the setup into its own
script and provides dedicated functions to be executed at a later point in time.

A **new** env variable was added: `USER_PROVISIONG` which provides a
better way of defining which method / protocol to use when it comes to
setting up users. This way, the `ENABLE_LDAP` variable is deprecated,
but all of this is backwards compatible due to a "compatibility layer", a function provided by the new variables script.

This is not a breaking change. It mostly refators internal scripts. The
only change facing the user-side is the deprecation of `ENABLE_LDAP`. We
can prolong the period of deprecation for this variable as long as we
want, because the new function that ensures backwards compatibility
provides a clean interface for the future.

With `_log`, the `_notify` method wa rendered obsolete. `_notify` was

The new `_log` function properly uses log levels such as `trace`,
`debug`, `info`, `warn` and `error`. It provides a cleaner solution
and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it).

Adjust envrionment variables - more sensible defaults (#2428)
The new setup will now set env variables on one place and on one place
only. The old setup used two separate places wich is not DRY and
confusing.

Some default values changed:

1. PFLOGSUMM_TRIGGER: logrotate => none
2. REPORT_SENDER: mailserver-report@HOSTNAME => mailserver-report@DOMAIN
3. REPORT_RECIPIENT: "0" => POSTMASTER_ADDRESS

One env variable was renamed: REPORT_INTERVAL => LOGROTATE_INTERVAL

I believe these defaults to be more sensible, especially the REPORT_RECIPIENT
address. The PFLOGSUMM_TRIGGER value was changed to `none` because otherwise
people would start getting daily Postfix log summary reports automatically.
Now, this is opt-in, and reports are sent only when enabled properly.

Some of the variables changed were marked as deprecated. I removed the note,
as the variables now bear some (sane) defaults again for other variables
(i.e.) REPORT_RECIPIENT is now default for other recipient addresses.
