How can they do this
Reviewed on 2021-04-13T12:58:44
We have in the last couple of weeks set up a new email address for a new employee.Then we receive the blocked message from this company. At first I thought it was spam itself only to check the company out. How can they do this? Luckily our email hosting company can sort this out.

I was approached by a client who was somehow talked into buying a fake service of Spamhaus to remove his ip address from a blacklist.
This is a scam and my friend never was on any blacklist,Spamhaus just shows every IP you enter in the box as blacklisted.
If you have any doubts if you IP has been blacklisted use whatismyip blacklist-check for a correct diagnostic and free.
If your IP was blacklisted, there are cheaper ways to fix this and some are free:
Many ISP's designate a static IP address, usually those addresses almost never change for a client except that most Docsis modems and probably others if you leave them "disconnected" for several hours or a day they will lose the assigned IP address and will get assigned another one.
If you run a business and are managing multiple Facebook and Twitter accounts this WILL put you on a blacklist because they detect this as spam.
If you run a legitimate business then you should connect to these services using a known VPN service.
Because VPN services line NordVPN, ExpressVPN etc... have contracts with social networks and other services that allows them to be whitelisted and every IP address coming from their servers will be on a whitelist.
Don't fall for the Spamhaus scam.

I was blacklisted for notifying my friends of my email address change
Reviewed on 2020-06-15T16:26:11
I switched my ISP from Cox to Centurylink and sent out an email to 80 of my friends and colleagues,announcing a change to my email address. I was blacklisted by Spamhaus. I tried to remove the address twice with no results. Spamhaus's disclaimer is another version of Pontius Pilot's declaration that it doesn't interfere with the actions of its customers. The upshot is that I am unable to email one of my clients, Texas Tech University. Spamhaus declares that the failure of my emails to reach TTU is TTU's responsibility. Good luck with that defense when the end of the world occurs.

I am a domainer buying/selling domains
Registered a domain on 5th April 2020
No website, no email,associated with the domain, just a placeholder page.
On 9th came to know it is listed in DBL
The removal page page does not accept free emails.
Created an email on the domain and sent request.
No reply or link came them.
What kind of joke is this?

Reviewed on 2020-01-10T23:31:59
Spamhaus sometimes blacklists a range of IP addresses making innocent IP addresses victims of spammers and the incompetence of Spamhaus.No blacklist is perfect, so Spamhaus's false positive errors are not a big problem per se. The worst part of Spamhaus is its slow response or no response to requests of unlisting innocent IPs. It may take days to take an innocent IP off their blacklists, affecting business severely.
Many services respond to requests for removing innocent IPs from blacklists in minutes.
Spamhaus is not a good choice for spam blacklists.

I can't keep my ISP delisted
Reviewed on 2019-12-27T02:53:05
I'm just a private individual, and I can't keep my ISP delisted! They keep blocking me,and at least once the referenced ISP wasn't mine. They've been plaguing me all day, even though I have gone through all their steps. This is about the sixth episode, and the frequency seems to be increasing. Nor did they respond to my email asking for help. Where do we report these guys?
