    Hello,
    What is needed for postfix to work properly?
    I heard a reverse DNS is needed, but how to do that?
    Thanks

    Thanks, and do you know where they mention all this in the official Postfix documentation???
    Thanks

    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.
