Question Enable DNS Caching with Plesk Firewall extension in use

Johnny9977

Basic Pleskian
Hi there,

I’m currently using the official Plesk Firewall extension to manage my ports, along with the Plesk E-Mail Security extension. The E-Mail Security extension recommends enabling local DNS caching to enhance DNSBL checks, and it provides a tutorial for doing so. According to the tutorial, I need to add “nameserver 127.0.0.1” to my /etc/resolv.conf.

After following these steps, everything works fine, and the badge turns green. However, when I modify my firewall settings, my changes to /etc/resolv.conf are overwritten.

Do you have any suggestions on how to prevent this from happening?


Thanks in advance!
