  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Automatically block attacking ips

Y

Basic Pleskian
I'm getting a whole lot of attacks it appears and I'd like to automatically perform an nslookup or if it is an ip add it directly to the firewall to block all incoming traffic from these attackers. What is available to allow this type of functionality?

Here is a sample of what I've been seeing in my logs:

I apologize, I had not seen this answer previously that I was given to the same question some time ago:
