Be aware: zen.spamhaus.org marks a lot of private ip adresses, which don't send out spam and fill out regular forms.
I would recommend using primarily uceprotect level 1, 2 and also 3.

you do know that uceprotect is even worst than spamhaus.
At least spamhaus has a usable delisting process and keeps its listings up to date.

Not to mention uceprotect charges for removal even if it is not your problem.

Hello.
The script works ok on A records, but actually due to my type of work i do not use A records but we add Name Servers. Can you please help me on how to change the script to work on NS.

Regards,
Mond
