Max Defers in cPanel

Introduction

Max Defers is a cPanel feature that allows the user to set a limit on the number of deferred email messages that can be stored in the mail queue. When a message is deferred, it means the mail server is temporarily unable to deliver it to the recipient's mail server. By default, cPanel allows an unlimited number of deferred messages, which can sometimes cause performance issues. In this article, we will learn how to configure and manage the Max Defers feature in cPanel.
