I do not send spam! Why did I receive the abuse warning?

If legitimate emails are being sent, then please make sure the recipient email addresses were acquired using confirmed opt-in (COI), and that there is an easy method to opt-out (unsubscribe). Please also check that you have a valid PTR record for the IP, and consider setting up SPF and DKIM, if not already configured.

WORLDBUS support can help you to prevent unwanted spam emails if you’re in trouble situation.

How to stop spamming?

If you don’t have any plan to send emails at all, we are strongly recommend to close 25, 465, 587 ports in your service firewall.

By running the following script on Linux operating systems on a regular basis with CronJob, you can automatically block the IPs that are known as spammers in the spamhaus system. This script automatically Block/Unblock the ports based on the status of the spamhaus.org.

Spamhaus Script:
wget http://worldbus.co/Spamhaus.sh

However, it is possible that your email content or sending behavior may have triggered the warning. To stop spamming, you can take measures such as:

  • Reviewing your email content and ensuring it is relevant and non-promotional
  • Updating your email list and removing inactive or uninterested recipients
  • Providing an easy way for recipients to unsubscribe from your emails
  • Limiting the frequency of your email sends
  • Avoiding the use of trigger words or phrases that could classify your emails as spam

By taking these steps, you can minimize the chances of being flagged as a spammer and maintain good email deliverability.
