How we can check multiple IPs blacklist at a single hit?
Any idea , please?
I think you must change the system to ‘post’. Because anyone can see the users IP address from the address bar and this is quite dangerous
@TecDeveloper: Good idea, i changed the form to post.
@msl-durgesh Maybe this could help or inspire (https://dnsbl.tebe.ch, https://github.com/tbreuss/dns-blacklist-check)
Thanks @istiak101. I will go through your referencies and remove the UceProect RBLs.
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
It works perfectly. Grete work
Thank You!
Thanks @LevinFaber, I removed the sbl and xbl domains. For everyone interested here is the link https://www.spamhaus.org/zen/ with more information.
