Hi William, I am a colleague of Marcus. Now we find out, that the whitelist works definetely fine. The problem is, that the sender marks its outgoing mails with "X-ESET-AntiSpam: SPAM;... " Our filter (after eset) can not recognize which ESET-instance set this header entry. Is it possible to change "X-ESET-AntiSpam: " into an individual entry. We found no config entry for this.
