* 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. Co-authored-by: georglauterbach <44545919+georglauterbach@users.noreply.github.com> * adjusted rspamd test to refactored test helper functions * improve documentation * apply suggestions from code review (no. 1 by @polarthene) Co-authored-by: Brennan Kinney <5098581+polarathene@users.noreply.github.com> * streamline heredoc (EOM -> EOF) * adjust rspamd test (remove unnecessary run arguments) Co-authored-by: Brennan Kinney <5098581+polarathene@users.noreply.github.com>

!!! warning "Implementation of Rspamd into DMS is WIP!"
|
|
|
|
## About
|
|
|
|
Rspamd is a "fast, free and open-source spam filtering system". It offers high performance as it is written in C. Visit [their homepage][homepage] for more details.
|
|
|
|
## Integration & Configuration
|
|
|
|
We provide a very simple but easy to maintain setup of RSpamd. The proxy worker operates in [self-scan mode][proxy-self-scan-mode]. This simplifies the setup as we do not require a normal worker. You can easily change this though by [overriding the configuration by DMS](#providing-overriding-settings).
|
|
|
|
### Providing & Overriding Settings
|
|
|
|
DMS brings sane default settings for Rspamd. They are located at `/etc/rspamd/local.d/` inside the container (or `target/rspamd/local.d/` in the repository). If you want to change these settings and / or provide your own settings, you can
|
|
|
|
1. place files at `/etc/rspamd/override.d/` which will override Rspamd settings and DMS settings
|
|
2. (re-)place files at `/etc/rspamd/local.d/` to override DMS settings and merge them with Rspamd settings
|
|
|
|
You can find a list of all Rspamd modules [on their website][modules].
|
|
|
|
### DMS' Defaults
|
|
|
|
You can choose to enable ClamAV, and Rspamd will then use it to check for viruses. Just set the environment variable `ENABLE_CLAMAV=1`.
|
|
|
|
DMS disables certain modules (clickhouse, dkim_signing, elastic, greylist, rbl, reputation, spamassassin, url_redirector, metric_exporter) by default. We believe these are not required in a standard setup, and needlessly use resources. You can re-activate them by replacing `/etc/rspamd/local.d/<MODULE>.conf` or overriding DMS' default with `/etc/rspamd/override.d/<MODULE>.conf`.
|
|
|
|
DMS does not set a default password for the controller worker. You may want to do that yourself. In setup where you already have an authentication provider in front of the Rspamd webpage, you may add `secure_ip = "0.0.0.0/0";` to `worker-controller.inc` to disable password authentication inside Rspamd completely.
|
|
|
|
## Missing in DMS' Current Implementation
|
|
|
|
We currently lack easy integration for DKIM signing. We use OpenDKIM though which should work just as well. If you want to use Rspamd for DKIM signing, you need to provide all settings yourself and probably also set the environment `ENABLE_OPENKIM=0`. Do not confuse the signing with checking DKIM signatures of other emails: Rspamd will check signatures from other emails, just not sign yours in the default configuration.
