Is there a way to set a cpanel/whm account to only allow traffic to and from using assigned emails. No other email addresses in or out will be processed. In other words every email that goes through the mail server (in or out) must be related to a current assigned email account, if its not then it gets destroyed. thanks :)

  Hello @durangod, Thank you for contacting cPanel! You can suspend incoming and outgoing mail for individual email accounts via the Email Accounts page in cPanel. For more information, refer to the "Restrictions" section on the following page: For example, you could create a rule with these options:

  • To
  • does not contain
  • your current assigned email account
  • Action: Discard

  Lastly, another option you should be aware of is that you can disable outgoing mail for a whole cPanel account using the suspend_outgoing_email
