+## [Unreleased](https://github.com/docker-mailserver/docker-mailserver/compare/v14.0.0...HEAD)
 
 > **Note**: Changes and additions listed here are contained in the `:edge` image tag. These changes may not be as stable as released changes.
 
-### Updates
-
-- **Documentation:**
-  - Added a compatibility note for a Dovecot + Solr 9.8 breaking change ([#4433](https://github.com/docker-mailserver/docker-mailserver/pull/4433))
-- **Internal:**
-  - Refactored `setup config dkim` (`open-dkim`) ([#4375](https://github.com/docker-mailserver/docker-mailserver/pull/4375))
-
-## [v15.0.2](https://github.com/docker-mailserver/docker-mailserver/releases/tag/v15.0.2)
-
-### Fixes
-
-- **Postfix**
-  - Avoid modifying the message body when filtering sender headers. This regression was introduced from [#4120](https://github.com/docker-mailserver/docker-mailserver/pull/4120) as part of DMS v15.0.0 ([#4429](https://github.com/docker-mailserver/docker-mailserver/pull/4429))
-
-## [v15.0.1](https://github.com/docker-mailserver/docker-mailserver/releases/tag/v15.0.1)
-
-### Added
-
-- **Internal:**
-  - Added the Smallstep `step` CLI command for future internal usage ([#4376](https://github.com/docker-mailserver/docker-mailserver/pull/4376))
-
-### Fixes
-
-- **Postfix:**
-  - `setup email restrict` generated configs now only prepend to `dms_smtpd_sender_restrictions` ([#4379](https://github.com/docker-mailserver/docker-mailserver/pull/4379))
-- **Rspamd:**
-  - Change detection support now monitors all files found within the DMS _Config Volume_ Rspamd directory ([#4418](https://github.com/docker-mailserver/docker-mailserver/pull/4418))
-- **Internal:**
-  - A permissions fix for `/var/log/mail` that was [added in DMS v15]((https://github.com/docker-mailserver/docker-mailserver/pull/4374)) no longer encounters an error when no log files are present during a container restart, such as with a `tmpfs` volume mount ([#4391](https://github.com/docker-mailserver/docker-mailserver/pull/4391))
-  - The DMS _State Volume_ (`/var/mail-state`) will now ensure it's file tree is accessible for services when the volume was created with missing executable bit ([#4420](https://github.com/docker-mailserver/docker-mailserver/pull/4420))
-  - The DMS _Config Volume_ (`/tmp/docker-mailserver`) now correctly updates permissions on container restarts ([#4417](https://github.com/docker-mailserver/docker-mailserver/pull/4417))
-
-### Updates
-
-- **Internal:**
-  - Minor improvements to `_install_utils()` in `packages.sh` ([#4376](https://github.com/docker-mailserver/docker-mailserver/pull/4376))
-
-## [v15.0.0](https://github.com/docker-mailserver/docker-mailserver/releases/tag/v15.0.0)
-
 ### Breaking
 
 - **saslauthd** mechanism support via ENV `SASLAUTHD_MECHANISMS` with `pam`, `shadow`, `mysql` values has been removed. Only `ldap` and `rimap` remain supported ([#4259](https://github.com/docker-mailserver/docker-mailserver/pull/4259))
 - **getmail6** has been refactored: ([#4156](https://github.com/docker-mailserver/docker-mailserver/pull/4156))
   - The [DMS config volume](https://docker-mailserver.github.io/docker-mailserver/v15.0/config/advanced/optional-config/#volumes) now has support for `getmailrc_general.cf` for overriding [common default settings](https://docker-mailserver.github.io/docker-mailserver/v15.0/config/advanced/mail-getmail/#common-options). If you previously mounted this config file directly to `/etc/getmailrc_general` you should switch to our config volume support.
+  - IMAP/POP3 example configs added to our [`config-examples`](https://github.com/docker-mailserver/docker-mailserver/tree/v15.0.0/config-examples/getmail).
+  - ENV [`GETMAIL_POLL`](https://docker-mailserver.github.io/docker-mailserver/v15.0/config/environment/#getmail_poll) now supports values above 30 minutes.
+  - Added `getmail` as a new service for `supervisor` to manage, replacing cron for periodic polling.
   - Generated getmail configuration files no longer set the `message_log` option. Instead of individual log files per config, the [default base settings DMS configures](https://github.com/docker-mailserver/docker-mailserver/tree/v15.0.0/target/getmail/getmailrc_general) now enables `message_log_syslog`. This aligns with how other services in DMS log to syslog where it is captured in `mail.log`.
   - Getmail configurations have changed location from the base of the DMS Config Volume, to the `getmail/` subdirectory. Any existing configurations **must be migrated manually.**
-  - **DMS v14 mistakenly** relocated the _getmail state directory_ to the _DMS Config Volume_ as a `getmail/` subdirectory.
+  - DMS v14 mistakenly relocated the _getmail state directory_ to the _DMS Config Volume_ as a `getmail/` subdirectory.
     - This has been corrected to `/var/lib/getmail` (_if you have mounted a DMS State Volume to `/var/mail-state`, `/var/lib/getmail` will be symlinked to `/var/mail-state/lib-getmail`_).
     - To preserve this state when upgrading to DMS v15, **you must manually migrate `getmail/` from the _DMS Config Volume_ to `lib-getmail/` in the _DMS State Volume_.**
-  - `setup email delete <EMAIL ADDRESS>` now requires explicit confirmation if the mailbox data should be deleted ([#4365](https://github.com/docker-mailserver/docker-mailserver/pull/4365)).
+  - Added missing `debug getmail` subcommand to `setup` ([#4346](https://github.com/docker-mailserver/docker-mailserver/pull/4346))
-- **Rspamd:** Removed deprecated file path check (_DMS config volume: `./rspamd-modules.conf` => `./rspamd/custom-commands.conf`_) ([#4373](https://github.com/docker-mailserver/docker-mailserver/pull/4373))
+- **removed `VERSION`** file that was used for checking version updates ([#3677](https://github.com/docker-mailserver/docker-mailserver/issues/3677),[#4321](https://github.com/docker-mailserver/docker-mailserver/pull/4321))
+
+### Security
+
+- **Fail2ban:**
+  - Ensure a secure connection, when downloading the fail2ban package ([#4080](https://github.com/docker-mailserver/docker-mailserver/pull/4080))
 
 ### Added
 
 - **Internal:**
   - Add password confirmation to several `setup` CLI subcommands ([#4072](https://github.com/docker-mailserver/docker-mailserver/pull/4072))
-  - Added a `debug getmail` subcommand to `setup` ([#4346](https://github.com/docker-mailserver/docker-mailserver/pull/4346))
 
 ### Updates
 
-- **Internal:**
+- **Fail2ban:**
-  - **Removed `VERSION` file** from the repo. Releases of DMS prior to v13 (Nov 2023) would check this to detect new releases ([#3677](https://github.com/docker-mailserver/docker-mailserver/issues/3677), [#4321](https://github.com/docker-mailserver/docker-mailserver/pull/4321))
+  - Updated to version [`1.1.0`](https://github.com/fail2ban/fail2ban/releases/tag/1.1.0) ([#4045](https://github.com/docker-mailserver/docker-mailserver/pull/4045))
-  - During image build, ensure a secure connection when downloading the `fail2ban` package ([#4080](https://github.com/docker-mailserver/docker-mailserver/pull/4080))
 - **Documentation:**
   - Account Management and Authentication pages have been rewritten and better organized ([#4122](https://github.com/docker-mailserver/docker-mailserver/pull/4122))
   - Add a caveat for `DMS_VMAIL_UID` not being compatible with `0` / root ([#4143](https://github.com/docker-mailserver/docker-mailserver/pull/4143))
-- **Getmail:** ([#4156](https://github.com/docker-mailserver/docker-mailserver/pull/4156))
-  - Added `getmail` as a new service for `supervisor` to manage, replacing cron for periodic polling.
-  - IMAP/POP3 example configs added to our [`config-examples`](https://github.com/docker-mailserver/docker-mailserver/tree/v15.0.0/config-examples/getmail).
-  - ENV [`GETMAIL_POLL`](https://docker-mailserver.github.io/docker-mailserver/v15.0/config/environment/#getmail_poll) now supports values above 30 minutes.
 - **Postfix:**
   - By default opt-out from _Microsoft reactions_ for outbound mail ([#4120](https://github.com/docker-mailserver/docker-mailserver/pull/4120))
-- **Rspamd:**
+- Updated `jaq` version from `1.3.0` to `2.0.0` ([#4190](https://github.com/docker-mailserver/docker-mailserver/pull/4190))
-  - Updated GTube settings and tests ([#4191](https://github.com/docker-mailserver/docker-mailserver/pull/4191))
+- Updated Rspamd GTube settings and tests ([#4191](https://github.com/docker-mailserver/docker-mailserver/pull/4191))
-- Updated externally installed software ([#4357](https://github.com/docker-mailserver/docker-mailserver/pull/4357)):
-  - `DOVECOT_COMMUNITY_REPO=1` custom image build ARG now supports the latest Dovecot [`2.4.x`](https://github.com/dovecot/core/releases/tag/2.4.0) (_DMS provides Dovecot `2.3.19` by default_)
-  - Dovecot FTS Xapian module (`1.7.12` => [`1.9.0`](https://github.com/grosjo/fts-xapian/releases/tag/1.9))
-  - `jaq` (`1.3.0` => [`2.1.0`](https://github.com/01mf02/jaq/releases/tag/v2.1.0))
-  - Fail2Ban (`1.0.2-2` => [`1.1.0`](https://github.com/fail2ban/fail2ban/releases/tag/1.1.0)) ([#4045](https://github.com/docker-mailserver/docker-mailserver/pull/4045))
-  - Rspamd (`3.8.4` => [`3.11.0`](https://github.com/rspamd/rspamd/releases/tag/3.11.0)) - Implicitly upgraded during image build, as the third-party repo lacks version pinning support.
 
 ### Fixes
 
 - **Dovecot:**
   - The logwatch `ignore.conf` now also excludes Xapian messages about pending documents ([#4060](https://github.com/docker-mailserver/docker-mailserver/pull/4060))
-  - `dovecot-fts-xapian` plugin was updated, fixing a regression with indexing ([#4095](https://github.com/docker-mailserver/docker-mailserver/pull/4095))
+  - `dovecot-fts-xapian` plugin was updated to `1.7.13`, fixing a regression with indexing ([#4095](https://github.com/docker-mailserver/docker-mailserver/pull/4095))
   - The "dummy account" workaround for _Dovecot Quota_ feature support no longer treats the alias as a regex when checking the Dovecot UserDB ([#4222](https://github.com/docker-mailserver/docker-mailserver/pull/4222))
 - **LDAP:**
-  - Correctly apply a compatibility fix for OAuth2 introduced in DMS `v13.3.1` which had not been applied to the actual LDAP config changes ([#4175](https://github.com/docker-mailserver/docker-mailserver/pull/4175))
+  - Correctly apply a compatibility fix for OAuth2 introduced in DMS v13.3.1 which had not been applied to the actual LDAP config changes ([#4175](https://github.com/docker-mailserver/docker-mailserver/pull/4175))
 - **Internal:**
   - The main `mail.log` (_which is piped to stdout via `tail`_) now correctly begins from the first log line of the active container run. Previously some daemon logs and potential warnings/errors were omitted ([#4146](https://github.com/docker-mailserver/docker-mailserver/pull/4146))
+  - Fixed a regression introduced in v14 where `postfix-main.cf` appended `stderr` output into `/etc/postfix/main.cf`, causing Postfix startup to fail ([#4147](https://github.com/docker-mailserver/docker-mailserver/pull/4147))
   - `start-mailserver.sh` removed unused `shopt -s inherit_errexit` ([#4161](https://github.com/docker-mailserver/docker-mailserver/pull/4161))
-  - Fixed a regression introduced in DMS v14 where `postfix-main.cf` appended `stderr` output into `/etc/postfix/main.cf`, causing Postfix startup to fail ([#4147](https://github.com/docker-mailserver/docker-mailserver/pull/4147))
-  - Fixed a regression introduced in DMS v14 to better support running `start-mailserver.sh` with container restarts, which now only skip calling `_setup()` ([#4323](https://github.com/docker-mailserver/docker-mailserver/pull/4323#issuecomment-2629559254), [#4374](https://github.com/docker-mailserver/docker-mailserver/pull/4374))
-  - The command `swaks --help` is now functional ([#4282](https://github.com/docker-mailserver/docker-mailserver/pull/4282))
 - **Rspamd:**
   - DKIM private key path checking is now performed only on paths that do not contain `$` ([#4201](https://github.com/docker-mailserver/docker-mailserver/pull/4201))
+- The command `swaks --help` is now functional ([#4282](https://github.com/docker-mailserver/docker-mailserver/pull/4282))

+```txt
+COMMAND ARGUMENT1 ARGUMENT2 ARGUMENT3
+```
 
-DMS will apply this config when you provide `rspamd/custom-commands.conf` in your DMS Config volume. Configure it with directive lines as documented below.
+where `COMMAND` can be:
 
-!!! note "Only use this feature for `option = value` changes"
+1. `disable-module`: disables the module with name `ARGUMENT1`
+2. `enable-module`: explicitly enables the module with name `ARGUMENT1`
+3. `set-option-for-module`: sets the value for option `ARGUMENT2` to `ARGUMENT3` inside module `ARGUMENT1`
+4. `set-option-for-controller`: set the value of option `ARGUMENT1` to `ARGUMENT2` for the controller worker

+### Adjusting and Extending The Very Basic Configuration
 
-??? example
+Rspamd is running, but you want or need to adjust it? First, create a file named `custom-commands.conf` under `docker-data/dms/config/rspamd` (which translates to `/tmp/docker-mailserver/rspamd/` inside the container). Then add your changes:
 
-    ```conf title="rspamd/custom-commands.conf"
+1. Say you want to be able to easily look at the frontend Rspamd provides on port 11334 (default) without the need to enter a password (maybe because you already provide authorization and authentication). You will have to adjust the controller worker: `set-option-for-controller secure_ip "0.0.0.0/0"`.
-    # If you're confident you've properly secured access to the rspamd web service/API (Default port: 11334)
+2. Do you additionally want to enable the auto-spam-learning for the Bayes module? No problem: `set-option-for-module classifier-bayes autolearn true`.
-    # with your own auth layer (eg: reverse-proxy) you can bypass rspamd requiring credentials:
+3. But the chartable module gets on your nerves? Easy: `disable-module chartable`.
-    # https://rspamd.com/doc/workers/controller.html#controller-configuration
+
+??? example "What Does the Result Look Like?"
+    Here is what the file looks like in the end:
+
+    ```bash
+    # See 1.
+    # ATTENTION: this disables authentication on the website - make sure you know what you're doing!
     set-option-for-controller secure_ip "0.0.0.0/0"
 
-    # Some settings aren't documented well, you may find them in snippets or Rspamds default config files:
+    # See 2.
-    # https://rspamd.com/doc/tutorials/quickstart.html#using-of-milter-protocol-for-rspamd--16

-## Advanced Configuration
-
 ### DKIM Signing
 
 There is a dedicated [section for setting up DKIM with Rspamd in our documentation][docs::dkim-with-rspamd].
 
 ### ARC (Authenticated Received Chain)
 
-[ARC][wikipedia::arc] support in DMS is opt-in via config file. [Enable the ARC Rspamd module][rspamd-docs::arc] by creating a config file at `docker-data/dms/config/rspamd/override.d/arc.conf`.
+ARC is not set up by default, but you can easily enable it by adding a file called `arc.conf` to `docker-data/dms/config/rspamd/override.d/`. ARC can use DKIM keys that you should have already created. The configuration file could then contain the following:
 
-!!! example
+```conf
+sign_local = true;
+sign_authenticated = true;
 
-    For each mail domain you have DMS manage, add the equivalent `example.com` sub-section to `domain` and adjust the `path` + `selector` fields as necessary.
+domain {
-
+    <DOMAIN NAME> {
-    ```conf title="rspamd/override.d/arc.conf"
+        # Change the path here to your actual private key
-    sign_local = true;
+        path = "/tmp/docker-mailserver/rspamd/dkim/rsa-2048-mail-<DOMAIN NAME>.private.txt";
-    sign_authenticated = true;
+        # Changhe the selected if you chose a non-default one
-
-    domain {
-        example.com {
-            path = "/tmp/docker-mailserver/rspamd/dkim/rsa-2048-mail-example.private.txt";
         selector = "mail";
     }
-    }
+}
-    ```
+```
-
-!!! tip "Using a common keypair"
-
-    As with DKIM, the keypair can be shared across your configured domains.
-
-    Your ARC config can share the same DKIM private key + selector (_with associated DNS record for the public key_).
 
 ### _Abusix_ Integration
 
 This subsection provides information about the integration of [Abusix][abusix-web], "a set of blocklists that work as an additional email security layer for your existing mail environment". The setup is straight-forward and well documented:

-### Compatibility
-
-Since Solr 9.8.0 was released (Jan 2025), a breaking change [deprecates support for `<lib>` directives][solr::9.8::lib-directive] which is presently used by the Dovecot supplied Solr config (`solr-config-9.xml`) to automatically load additional jars required.
-
-To enable support for `<lib>` directives, add the following ENV to your `solr` container:
-
-```yaml
-services:
-  solr:
-    environment:
-      SOLR_CONFIG_LIB_ENABLED: true
-```
-
-!!! warning "Solr 10"
-
-    From the Solr 10 release onwards, this opt-in ENV will no longer be available.
-
-    If Dovecot has not updated their example Solr config ([upstream PR][dovecot::pr::solr-config-lib]), you will need to manually modify the Solr XML config to remove the `<lib>` directives and replace the suggested ENV `SOLR_CONFIG_LIB_ENABLED=true` with `SOLR_MODULES=analysis-extras`.
