Rspamd communigate pro1/24/2024 ![]() Providing Custom Settings & Overriding Settings ManuallyĭMS brings sane default settings for Rspamd. Otherwise, you might not be able ( see this Spamhaus post) to make use of the block lists. it should be a non-public & recursive resolver. If you want to use DNSBLs, try to use your own DNS resolver and make sure it is set up correctly, i.e. This evaluation is a best effort though, so if the DNSBL operators change or add return codes, it may take a while for Rspamd to adjust as well. Rspamd will try to mitigate some of them by properly evaluating all return codes. There are a variety of issues involved when using DNSBLs. When the RBL module is enabled, Rspamd will do a variety of DNS requests to (amongst other things) DNSBLs. Whether an RBL or a DNSBL is queried depends on where the domain name was obtained: RBL servers are queried with IP addresses extracted from message headers, DNSBL server are queried with domains and IP addresses extracted from the message body. As a consequence, Rspamd will perform DNS lookups to a variety of blacklists. RBLs (Realtime Blacklists) / DNSBLs (DNS-based Blacklists) Just set the environment variable ENABLE_CLAMAV=1. You can choose to enable ClamAV, and Rspamd will then use it to check for viruses. We believe these are not required in a standard setup, and they would otherwise needlessly use system resources. Disabled By DefaultĭMS disables certain modules (clickhouse, elastic, greylist, neural, reputation, spamassassin, url_redirector, metric_exporter) by default. You can find a list of all Rspamd modules on their website. If you have an external instance of Redis to use, the internal Redis service can be opt-out via setting the ENV ENABLE_RSPAMD_REDIS=0 ( link also details required changes to the DMS rspamd config). We adjust this file when enabling the internal Redis service. Redis uses /etc/redis/nf for configuration. With the volume mount the snapshot will restore the Redis data across container restarts, and provide a way to keep backup. Redis is configured to persist it's data via RDB snapshots to disk in the directory /var/lib/redis ( which is a symbolic link to /var/mail-state/lib-redis/ when ONE_DIR=1 and a volume is mounted to /var/mail-state/). When Rspamd is enabled, we implicitly also start an instance of Redis in the container. In setups where you already have an authentication provider in front of the Rspamd webpage, you may want to set the secure_ip option to "0.0.0.0/0" for the controller worker to disable password authentication inside Rspamd completely. You can easily change this though by overriding the configuration by DMS.ĭMS does not set a default password for the controller worker. This simplifies the setup as we do not require a normal worker. The proxy worker operates in self-scan mode. The Default Configuration Mode of Operation The following environment variables are related to Rspamd: For those running Rspamd on ARM64, we recommend disabling the DKIM signing module if you don't use it. Maintainers noticed only few differences, some of them with a big impact though. The current version difference is two minor versions (AMD64 is at version 3.4, ARM64 at 3.2 ). We are currently doing a best-effort installation of Rspamd for ARM64 (from the Debian backports repository for Debian 11). Providing Custom Settings & Overriding SettingsĪdjusting and Extending The Very Basic Configuration You can also use Rspamd's web UI to learn ham and / or spam or to adjust certain settings of Rspamd.RBLs (Realtime Blacklists) / DNSBLs (DNS-based Blacklists) The bayes statistics are written to Redis as keys BAYES_HAM and BAYES_SPAM.īesides bayes, a local fuzzy storage is used to learn recurring patterns in text or images that indicate ham or spam. We configured the plugin to keep a sane ratio between spam and ham learns. Rspamd also auto-learns mail when a high or low score is detected (see ). This is achieved by using the Sieve plugin "sieve_imapsieve" and parser scripts. Rspamd learns mail as spam or ham when you move a message in or out of the junk folder to any mailbox besides trash.

Rspamd is used for AV handling, DKIM signing and SPAM handling. ![]() Trigger a resend of quarantine notifications Learn Spam or Ham from existing directory
