Hi,
Yeah that is why I prefer postfix config have the IP block or specific
host. At least I have a clear log of the reject. If I have it in
iptables there will be a log but feel its clearer in postfix what the
intent was.
Cheers,
Noah

Hi there,
I am hoping to have a blacklist file that stops postfix from accepting
email from specific IP or IP ranges.
I follow this tutorial and it does not working. I still receive email
from the IP addresses in the range:

Is there an option out there that actually works?
Not sure what operating system you are using but assuming it is Linux, I
just use firewalld to block all connections from the IP address.
Just don't do that permanently (or postfix reject permanently) as IP
addresses change and then you get situations where a legitimate server
with the IP address is blocked.
By the time it has been blocked a week, it probably is already on the
popular dynamic blacklists.
