Hello, What is needed for postfix to work properly? I heard a reverse DNS is needed, but how to do that? Thanks
There is tutorial: https://www.howtoforge.com/how-to-install-an-email-server-with-ispconfig-on-debian-10/ https://www.howtoforge.com/tutorial...vice-with-ispconfig/#nbspreverse-name-service
Reverse DNS isn't required for Postfix to work, but a lot of ESP's will block your email if you don't have it configured. I don't think this is in the postfix docs. Also, you should set up a SPF, DKIM, and DMARC record.
