Remove IP from Blacklist | Barracuda

IP blacklist:

IP could be blacklisted for many reason. If you broadcast spam or you have an infected PC, your IP could be blacklisted. And, when IP gets blacklisted, you can’t browse internet properly. As a result, many websites do not allow ‘blacklisted IP’ to access their server.

Similarly, E-mail server IP also gets blacklisted and it is very common. And, if it happens, you will see problems with email delivery.

Follow the steps to remove IP from blacklist:

At first, we need to check IP reputation from blacklist check site. Go to this website: https://mxtoolbox.com/.  The blacklist check will test an IP address against over 100 DNS based blacklists. (Commonly called Realtime blacklist, DNSBL or RBL)

1. Go to the blacklist tab. Put IP to check the blacklist.

2. Now we will see how to remove it from the blacklist. Click on the detail as the below picture.

 

3. In here, you can see a URL link. This is where you will know the reason for listing.

• Copy the link and open the URL in another tab.

4.  Scroll down the page and click on ‘I am not a robot’.

• Click the button – ‘Lookup IP reputation’.

 

5. Now fill up the required information, i.e. Suspected IP address, Email address, and phone number. Give a valid explanation to remove IP from the blacklist. After that, submit the request.
