Hi, we have a problem with Spam. We are receiving a lot of email Spam from other servers IP, and they are inventing email accounts with my domins hosted in my VPS service. Which is the better option to block them? To block IP by IP or to use an Anti-Spam.

  Hello :), If you are receiving spam mails then I will suggest you please enable SPF and DKMI on your server. Also to prevent mail abuse from your server, Please check following docs. How to Prevent Email Abuse - cPanel Knowledge Base - cPanel Documentation

  Hello, You may also find the RBL options and the "Reject SPF Failures" option available in "WHM >> Service Configuration >> Exim Configuration Manager >> Basic Editor" helpful:
