In cPanel how do you set up filtering to BLOCK all domains for both inbound and outbound emails and whitelist my company domains. I am looking to only allow inbound and outbound emails to be sent from 4 company domains and block employees from receiving and sending emails from all other domains. Emails are to be used for business purposes only and therefore all non-business domains need to be blocked. Thanks everyone.

  Hello :) It may be easier to setup this configuration with firewall rules instead of custom Exim ACL rules. You may want to try ensuring that only local connections are allowed for mail-related services. Or, you could also block a range of IP addresses (every range except your own) under "Access Lists" in "WHM Home " Service Configuration " Exim Configuration Manager". Thank you.
