* chore: Remove `SYS_PTRACE` capability from docs and configs
* chore: Remove `SYS_PTRACE` capability from tests
Doesn't seem to be required. It was originally added when the original change detection feature PR apparently needed it to function.
Dovecot master accounts can now be configured in DMS via `setup.sh`.
A master account is useful for administration purposes, or to perform mailbox backups of every user account over IMAP.

Removed typo "logs".
Removed warning that Docker volumes are strongly recommended, as this can lead new users in the wrong direction (bind mounts are now the default).
Altering line 8, mentioning the default of bind mounts.
* first adjustments to use Fail2Ban with nftables
* replace `iptables` -> `nftables` and adjust tests
nftables lists IPs a bit differently , so the order was adjusted for the
tests to be more flexible.
* line correction in mailserver.env
* change from `.conf` -> `.local` and remove redundant config
* revert HEREDOC to `echo`

* added new `_log` function
With `_log`, the `_notify` method wa rendered obsolete. `_notify` was
not completely removed due to test failures in `check-for-changes.sh`.
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).
* converted all helper script to new `_log` function
* converted all startup stacks to new `log` function
* `start-mailserver.sh` now uses new `_log` function
* final test and misc small script adjustments
* updated documentation
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.

* docs(deps): bump mkdocs-material to v8.2.1
* feat(docs): enable mermaid integration
Configuration based on https://squidfunk.github.io/mkdocs-material/reference/diagrams/?h=mermaid#configuration
* fix: allow yaml value mapping
* chore: Adopt mkdocs-material mermaid integration support
Supported by the docs generator now, we no longer need to rely on external image generator or live editor link (both relied on large base64 encoding of mermaid markup). SVG will be rendered by docs now, although a little different style (can be fixed with custom CSS).

* 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.
* adjusted content to PR suggestions
Using `set -ex` will exit the script as soon as a non-zero exit code is returned, such as when the docker image fails building the docs due to `build --strict` catching broken links. This also removes the need for `|| exit` when changing directory.
This seems fine for a small script, but AFAIK an alternative fix is just adding `|| exit` to the end of the `docker run` command too? There appears to be advice [against adopting `-e` carelessly](http://mywiki.wooledge.org/BashFAQ/105), while others [encourage `-e`](http://redsymbol.net/articles/unofficial-bash-strict-mode/). I know that several maintainers here have preference towards `set -e` so I've kept the original PR solution.
Additionally:
- `-x` is used to improve command visibility when reviewing the workflow log output.
- `--name` isn't necessary, but was part of the original PR.
- I've chosen not to include `-o pipefail`, only because no pipes are used in this script.
* docs(fix): Fix broken links
* ci(docs): Added inline docs
Extra documentation context for maintainers to quickly grok what's going on.
* chore(docs): Minor typo fix by wernerfred
Added from their related PR by request.
* docs(ssl): Adjust heading levels for provisioning sections
- Group provisioning sections under one heading level.
- Use `attr_list` syntax for headings to make the ToC sidebar entry less verbose.
* docs(ssl): Minor fixes
Typos, formatting.
* docs(ssl): Rephrase Traefik wildcard support
Split the line out into multiple with better phrasing.
* 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.
* chore: Add FQDN comment for `docker-compose.yml` example config
This was a community contributed guide from the Github Wiki prior to docs migration. I've rewritten it by restructuring the content, introducing numerical steps and revising some of the content, while removing third-party software that was unnecessary (the original authors and content related to their use-case, Moodle).
See the PR for further details and reference links regarding the original documents history.
The PR provides improved diff via separate commits scoping changes at the correct change bounds, unfortunately the full diff doesn't align to those boundaries well making it more difficult to review vs individual commits.
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.
