I try tuning rspamd to better detect spams my e-mail server gets. I think increasing spammines for e-mails where sending domaind lacks SPF and message is not DKIM saved would help. I found R_SPF_NA and R_DKIM_NA, which I guess mean message does not have SPF/DKIM. I thought I could add one or two spamminess points when that happens. But I can not find useful documentation. Only thing search engines find in website rspamd.com is https://rspamd.com/doc/modules/milter_headers.html which has one line about R_SPF_NA: Code: none = "R_SPF_NA"; That does not help much. Does requiering SPF and DKIM nowadays cause problems? What values are valid for those "variables" and how to set them?
