Without amending the main Exim configuration itself, is there a switch or external config option to prevent cPanel/WHM authenticated email users from relaying mail for domains and user accounts NOT configured on the server?
We're seeing a large number of compromised (weak passwords) on customer servers that are being used to send out spam with made-up email addresses. As the attackers have already successfully authenticated with the SMTP server, they can send whatever they like.
