Hello. I am upgrading services and would like to improve mail deliveries. DNSSEC is working correctly. The mails are sent and received, but it is difficult to prevent them from reaching the Spam folder in outllok or microsoft for example. I am with a clean configuration of "Perfect Server Automated ISPConfig 3 Installation" in Debian. The question is: What are the steps to follow to configure DANE correctly in this type of installation? (I apologize if this should not be asked here) Thank you very much.
Your should generate the DANE Record based on the certificate and add it to the zone in question. However, make sure you understand and know what your doing beforehand to not mess up a productive enviroenment.
I understand, thanks, I think the chain is fine as I have it, I will avoid implementing DANE. Regards
