    Hi everyone. I'm using latest 3.1.x version.
    I've a question on the subject "How To Configure Custom Postfix Bounce Messages" - I've followed this tutorial:
    https://www.howtoforge.com/configure-custom-postfix-bounce-messages

    and this indeed works, however, I've one small/big problem:

    Error message I change is displaying in the bounce-back message (I'm testing sending email to valid user but it's "Send copy to/forward email" does not exists):
    The problem is this last part:
    <email@tld.com>: user unknown

    Where exactly can I change this to something else? The bounce back message ends with "The mail system" and I can't find anywhere something like "user unknown", at least not with lower-case "user", not even in the /usr/share/doc/postfix and same location with /html
