Works with

• openSUSE Leap 15.4 -> tested

Role Variables

---

You can set the following variables to configure the role. Here listed are the variables and their default settings.

Firewall configuration (disable by default)

Value	Description	Default
unbound_nameservers	Nameservers to ask	"45.11.45.11 # DNS.SB"
rspamd_redis_connection	rspamd redis socket	"/var/run/redis/rspamd.sock"
rspamd_password	password for the rspamd web interface	"Q1"
rspamd_dkim_key_length	bit length of the rspamd dkim key	2048
rspamd_dkim_key_selector	selector for the DKIM key	2023

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: jellyfish
  roles:
     - { role: geekoops-rspamd, rspamd_dkim_key_length="2048" }

An advanced example for the imaginary jellyfish test server

- hosts: jellyfish
  roles:
     - role: geekoops-rspamd
       vars:
         rspamd_dkim_key_length: "2048"

Notes

rspamc learn_ham always failed for me even as root user. Specifying secure_ip = "" in /etc/rspamd/local.d/worker-controller.inc made it work in dovecot. A source for training data is here: https://spamassassin.apache.org/old/publiccorpus/ Note that currently rspamd needs 200 mails to start.
