  Hey there! In WHM >> Tweak Settings do you have "Restrict outgoing SMTP to root, exim, and mailman (FKA SMTP Tweak)" enabled? This will help keep automated scripts from sending messages. We also have this article here that might be helpful: How to find the source of spam emails

  Sorry about that - I was thinking outbound spam when this was inbound :D You could try this setting in WHM >> Exim Configuration Manager: "Allow DKIM verification for incoming messages" That would verify any message's DKIM, and if it doesn't pass it would not be delivered.

  There is always a risk of additional security measures having a negative impact on mail delivery. But, with how much spam you're receiving, it might be worth trying this. You can always turn it off later. I'm not entirely sure what the second image is supposed to be telling me.

  Greylisting would also be a great thing to turn on. It would cause a slight delay in the messages being received, but it would help ensure that only legitimate senders are able to reach your mailserver.

  Do yourself a favour and install MailScanner. Follow these instructions carefully: Free cPanel MailScanner Installer

  I don't have a good command line or API option for this edit as the interface makes several changes behind the scenes.
