Hi Bertrand, > forced: reject "Action set by DMARC"; score=nan (set by dmarc) It looks like you've set `actions` in `dmarc` module configuration- it's not recommendable to use that. If you need to enforce strict DMARC/SPF for certain domains you could use `whitelist` module for that: https://rspamd.com/doc/modules/whitelist.html Best, -AL.
