Hello,
Recently some of our emails have faced problems with being delivered. It turned out the reason for this was ‘Listed in DNSBL dnsbl.sorbs.net’. Further investigation showed that DOs IP range is listed in some spam blacklists. Is there anything at the moment that can be done with this?

Hello,
That’s no good! The best recommendation here would be to create a ticket with our Support team so we can investigate the blacklists that are including this IP address as well as potential delisting measures that can be taken. Alternatively, you’re always able to create a new Droplet in order to get a different IP address. The quickest way to do this would be via a snapshot and deploy as outlined here:

Hello there,
DNSBL blacklists can mark whole IP ranges indeed. This is really annoying as often it has nothing to do with your own mail reputation but you’ll still be affected.
Stopping spam is a constant fight, so we have implemented some restrictions on newer accounts, but this still does not guarantee all SPAM will be stopped.
In the meantime, you can use a site like MXtoolbox to check the mail reputation of your IP and send an email to https://mail-tester.com
Their tool will show how you can improve your mail score (outgoing mail delivery).
You can also use a third party mail provider like SendGrid in order to avoid issues like this one. I’ll also recommend checking this article:

You can reach to our support team as well regarding the mail reputation of the whole range.

Hope that this helps!
I have got the same problem. Could there be a form of some sort in the “manage” section of the dashboard to deal with this kind of things, please?
Hi I believe the listing in dnsbl.sorbs.net is actually administrated by Digitalocean.
While trying to add an exception for the digitalocean ip number I am using I found that it could not be added due to someone having registered the ip range 178.128.0.0/16 as “Listed and Immutable”. This range as can be seen here https://mxtoolbox.com/SuperTool.aspx?action=arin%3A178.128.0.0&run=toolpage# registred to Digitalocean.
