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.
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
* 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
* 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
The user management docs are now one page, because the division between
accounts and aliases is useless because there simply isn't enough
content to justify the split. I improved and updated the text a bit.
* docs: change some absolute links to relative links
* docs: change most hard-coded links to `edge` to point to `latest`
* Apply suggestions from code review
* docs: revert 404 page to edge and change canonical link to `latest
