* 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. |
