Leeching occurs when a user on your website, who has access to information that is supposed to be reserved for specific users (such as paid clients), is giving away your content by allowing other people to use their username and password.
cPanel has some built in protections to help minimize leeching.
cPanel's email authentication feature declares which servers are authorized to send mail, and helps receiving servers verify that the email they received is coming from a trusted sender.
If someone, such as a spammer or malicious actor, were to send a spoofed email claiming to be from a certain domain name, spam filters on the receiving end would detect that the email was not coming from an authorized server, and flag the message as possible spam or a possible phishing attempt.
In this final segment of the cPanel/WHM Admin Essentials webinar, cPanel's Technical Trainer Lee Latham explores: server load, what causes server load and corrective actions to take when your server load is excessive.
