I’m running an Ubuntu server on a droplet. This includes a webapplication which is able to send e-mails to users. One of my servers is now listed on the Spamhaus list. How is this possible?

Problem Solved, I requested Spamhaus to remove the IP-adress from the blacklist
Heya,
It’s quite common for Cloud provider’s IP addresses to appear in such lists.
Here are some common reasons why this might occur:
-
Email Sending Practices: If your web application sends a large volume of emails that are not compliant with best practices (like sending unsolicited emails, not including an unsubscribe option, or having a high bounce rate), it could be flagged as spam.
-
IP Reputation: If you’re using a shared hosting environment, the reputation of your IP address could be affected by the activities of other users on the same server.
-
Poor Configuration: Misconfigured mail servers can sometimes send emails in a way that triggers spam filters. Ensure that your mail server is properly set up with SPF, DKIM, and DMARC.
-
User Complaints: If recipients of your emails mark them as spam, this can harm your reputation and lead to being listed on blocklists.
Requesting your IP to be removed from Spamhaus should be as easy as clicking a few buttons and that should sort the problem out.
Because someone who was assigned that IP address in the past was spamming. You should ask Digital Ocean to give you a new IP address. It should be up to them to clear a spam history - not you.
