scripts: Rspamd stabilization pt. 2 (#3282)
* move modules adjustment file to new location

Because we link `/tmp/docker-mailserver/rspamd/override.d` to
`/etc/rspamd/override.d`, I think it makes sense to move the modules
adjustment file into `/tmp/docker-mailserver/rspamd/` as well.

I write the code in a way that it is backwards compatible for now, so
this is NOT a breaking change.

* minor improvement to `__rspamd__handle_user_modules_adjustments`

The expansion of `ARGUMENT3` is now done in a way that only adds the
whitespace in case the variable is set and not null.

* move test file structure to respect latest changes

Because we're now linking `rspamd/override.d/`, we can simplify the
setup a bit. But this requires a change in directory structure.

The current Rspamd test will be renamed to `rspamd_full.bats`, because I
plan on adding more tests in different files for different feature sets.
This is done to make this feature well-tested!

* improved and added tests to Rspamd-full

FYI: The line

```bats
_run_in_container grep 'sieve_global_extensions.*\+vnd\.dovecot\.pipe'
"${SIEVE_CONFIG_FILE}"
```

was testing a condition that should actually not be met, but when I
started working on this feature, I thought this was the correct
configuration. Adding the `assert_success` statements revealed this
wrong line.

I also added tests to check whether `override.d` is linked correctly.

* renamed: `rspamd.bats` => `rspamd_full.bats`

* added new tests for incomplete Rspamd feature set

We now test that warnings are emitted & features are disabled correctly.

* update documentation

scripts: Rspamd stabilization pt. 1 (#3261)
* added checks whether OpenDKIM/OpenDMARC/policyd-spf are enabled
* added functions to check if VAR is 0/0 or an int

and also added tests.

I also adjusted the test file to not run in a container, because there
is no need. This also decreases test time, which, in turn, increases
maintainers' happiness.

* added more checks to Rspamd setup

I added the helpers from the previous commit to the Rspamd setup to make
the whole setup more robust, and indicate to the user that an ENV
variable's value is incorrect.

While we did not issues for this in the past, I believe it to be
worthwhile for the future.

* added canonical directory for users to place files in

This dir is canonical with DMS's optional configuration dirs, as it
lives in well-known volume mounts. Hence, users will not need to adjust
`/etc/rspamd/override.d` manually anymore, or mount a volume to this
place.

The docs explain this now, but the DKIM page needs a slight update on
this too I guess. I will follow-up here.

* misc minor improvements
* use variables for common directories

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

* add tests

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

* tests(refactor): Improve consistency and documentation for test helpers (#3012)

* added `ALWAYS_RUN` target `Makefile` recipies (#3013)

This ensures the recipies are always run.

README.md and Documentation Update (#2389)
* follow up on #2383

Fixes a documentation error by which a list would not be rendered
correctly. This has been taken care of.

* update the `README.md`

I felt the need to update the README for several reasons:

1. LDAP issues that the core maintainers team cannot really resolve
2. Cleaning up the somewhat messy structure near the end

The first point goes without explanantion. The second points includes:

2.1. The tagging convention is now easier to read and understand
2.2. Some bullut points or notes have been inlined to "stick" more to
     the content that it actually belongs to
2.3. The note about the "old" `setup.sh` for DMS `10.1.0` has been
     removed as it is obsolete now. We encourage users to upgrade to
     `10.4.0` anyways.
2.4. The markdown code highlighting is now using `CONSOLE` instead of
     `BASH` because `CONSOLE` is more appropriate.
2.5. Capitalized headings
2.6. Updated the section about `./setup.sh help` to be in one place now
     instead of two
2.7. DKIM key generation does now not interfere with user account
     creation.

* docs(ssl): Adjust heading levels for provisioning sections

Typos, formatting.

* docs(ssl): Add FQDN section

We briefly mention the same info twice on the docs page, but as it applies to all provisioners in general, it's been given it's own detailed section with examples.

Single section to inform users about an FQDN, how it's configured and understood by `docker-mailserver` for both Docker CLI and `docker-compose.yml` variations.

Adds note about wildcard support and bare domains to clear up any confusion configuring FQDN for these two.

Additional note about Certbot using symlinks for it's cert storage.

docs: ssl.md - Revise letsencrypt section (#2209)
Below commit messages are roughly equivalent to what is listed on the PR. The PR provides additional linked resources for reference to support commit message statements.

---

* docs: Add CT log warning

- Added a warning to make users aware that using a public CA like _Let's Encrypt_ will publicly log information that may be somewhat sensitive, or undesirable to have historic records made public which cannot be redacted.

* docs: Revise the manual `certbot` guide

- The `letsencrypt` repo that was linked early in this guide now redirects to the [Certbot repo](https://github.com/certbot/certbot).

- More explicit volume mount instruction for CertBot; the local location was a tad vague.

- Better clarified `/etc/letsencrypt/live` contents structure, as well as FQDN info. Removed the misleading `fqdn:` from `docker-compose.yml` example snippet.

* docs: Revise certbot with Docker guide

- General rewrite of the Docker Certbot section with additional tips (_renewals with automation, and using a alternative CA_).

- Generalized tone and paths in content.

- Update volume mount paths to be consistent with recent normalization effort.

- Moved some instructions into inline-comments for script examples instead.

* docs: Revise Docker with `nginx-proxy` and `acme-companion`

- Break apart into individual steps, indenting content into the step as appropriate.

- Use normalized volume paths (`docker-data/<service>/` prefix).

- `letsencrypt-nginx-proxy-companion` has _changed project name to `acme-companion`_, and _transferred to new maintainers and the `nginx-proxy` organization_. This also affects the DockerHub image references.

- `acme-companion` has _switched from using `simp_le` to `acme.sh`_ for provisioning certificates. This requires mounting an additional volume for persisting provisioner state.

- The dummy container (_webmail_) is no longer `library/nginx`, just [`nginx`](https://hub.docker.com/_/nginx). This container also doesn't appear to be required. I've verified that the ENV can be given to the `mailserver` service container directly. Retained for now.

* docs: Revise Docker Compose with `nginx-proxy` and `acme-companion`

Heavy rewrite of this section. Like the previous commit mentions, this content was outdated. It has been simplified with improved documentation and reference links.

It also looks like there was a mistake in the existing config example as it uses the regular `nginx` image instead of `nginx-proxy`.

- The bulk of the `mailserver` service has been removed, users are advised to have an existing `docker-compose.yml` config for `docker-mailserver` and update only what is relevant to integrate with the cert provisioner.

- `DEBUG` is _false_ by default.

- The `networks:` portion of the example appears to be taken from upstream, _which that has since dropped it_. While we could continue to document this, I consider it more of an advanced config detail that we don't need to touch on in our docs.

- The `htpasswd` volume is unnecessary, only relevant if using _"Basic Authentication"_ to protect access to web service endpoints. `conf.d/` is also not required by default, it can be useful for the `standalone` mode (_documented as a `tip`_). Remaining volumes have inline-comments to document their purpose.

- `volumes_from:` is _not supported in v3 Compose format_, _only v2_ and the Docker CLI. I did not want to advise v2, so I've duplicated the volumes between the two containers instead. Internally `acme-companion` would rely on `volumes_from:` to identify the `nginx-proxy` container, it _provides alternative discovery methods_, the label is outdated and refers the legacy label (_their script logic is the same_); using the ENV `NGINX_PROXY_CONTAINER` seemed most appropriate and has been added.

- Upstream `acme-companion` docs only cover support for v2 Compose format. _There is a note regarding `nginx-proxy`_ having _volumes configured in it's Dockerfile_. Providing a volume for `/etc/nginx/dhparam` is required to avoid creating anonymous volumes each run of `nginx-proxy`. I've used a named data volume here to make it stick out more, it's not desirable and upstream should fix this, then we can drop it.

- I've also opted to only demonstrate the _Two Container (Basic) setup_ that upstream documents. Previously our docs have been showing _`docker-gen` with the Three Container (Advanced) setup_, which allows for not having the Docker API socket attached as a volume to a container exposed to the web. This reduces the security a bit, and I have not mentioned that on our docs. I could caution the reader with a link to upstream about the risk, but I don't think we should maintain the `docker-gen` setup.

* docs(fix): Update anchor links

These mismatched the current section headers they were meant to link to.

docs(chore): Normalize for consistency (#2206)
"Brief" summary/overview of changes. See the PR discussion or individual commits from the PR for more details.

---

Only applies to the `docs/content/**` content (_and `setup` command_). `target/` and `test/` can be normalized at a later date.

* Normalize to `example.com`

- Domains normalized to `example.com`: `mywebserver.com`, `myserver.tld`, `domain.com`, `domain.tld`, `mydomain.net`, `my-domain.tld`, `my-domain.com`, `example.org`, `whoami.com`.
- Alternative domains normalized to `not-example.com`: `otherdomain.com`, `otherdomain.tld`, `domain2.tld`, `mybackupmx.com`, `whoareyou.org`.
- Email addresses normalized to `admin@example.com` (in `ssl.md`): `foo@bar.com`, `yourcurrentemail@gmail.com`, `email@email.com`, `admin@domain.tld`.
- Email addresses normalized to `external-account@gmail.com`: `bill@gates321boom.com`, `external@gmail.com`, `myemail@gmail.com`, `real-email-address@external-domain.com`.
- **`faq.md`:** A FAQ entry title with `sample.domain.com` changed to `subdomain.example.com`.
- **`mail-fetchmail.md`:** Config examples with FQDNs for `imap`/`pop3` used `example.com` domain for a third-party, changed to `gmail.com` as more familiar third-party/external MTA.

* Normalize config volume path

- Normalizing local config path references to `./docker-data/dms/config/`: `./config/`, `config/`, \``config`\`, `/etc/` (_volume mount src path prefix_).
- Normalize DMS volume paths to `docker-data/dms/mail-{data,state,log}`: `./mail`, `./mail-state` `./data/mail`, `./data/state`, `./data/logs`, `./data/maildata`, `./data/mailstate`, `./data/maillogs`, (_dropped/converted data volumes: `maildata`, `mailstate`_).
- Other docker images also adopt the `docker-data/{service name}/` prefix.

* `ssl.md` - Use `dms/custom-certs` where appropriate.

* Apply normalizations to README and example `docker-compose.yml`

---

Common terms, sometimes interchangeably used or now invalid depending on context: `mail`, `mail container`, `mail server`, `mail-server`, `mailserver`,`docker-mailserver`, `Docker Mailserver`.

Rough transformations applied to most matches (_conditionally, depending on context_):

- 'Docker Mailserver' => '`docker-mailserver`'
- 'mail container' => '`docker-mailserver`' (_optionally retaining ' container'_)
- 'mail server' => 'mail-server' / '`docker-mailserver`'
- 'mail-server' => '`docker-mailserver`'
- 'mailserver' => 'mail-server' / '`docker-mailserver`'

Additionally I checked `docker run` (_plus `exec`, `logs`, etc, sub-commands_) and `docker-compose` commands. Often finding usage of `mail` instead of the expected `mailserver`

Additionally changes `mailserver` hostname in k8s to `mail` to align with other non-k8s examples.

fix: Enable DH parameters (ffdhe4096) by default (#2192)
This feature was originally introduced by the PR: https://github.com/docker-mailserver/docker-mailserver/pull/1463

- Assign default DH params to use via Dockerfile build instead of copy and update at runtime.
- Parameterized service names and paths.
- Refactor postfix and dovecot dh methods to wrap shared dh logic
- I don't see any value in checking the alternative service for dh params file to copy over, so that's now dropped too.
- Another conditional check is dropped and the default fallback message for existing DH params file is no longer relevant.
- Improved the remaining `_notify` messages. Collapsing the warning into a single logged message also seemed relevant.
- There is no apparent need for special handling with `ONE_DIR=1`. Dropped it.

- Refactor DH params  tests
- Combine custom and default DH param tests into single test file
- docs: Add instructions to use custom DH params

There is no official documented support for custom DH parameters. As no guarantee is provided, this is considered an internal change, not a breaking one.
