The correct answer is: It is used to receive emails from a mail server

The POP (Post Office Protocol) communications protocol is specifically designed for receiving emails from a mail server. It allows email clients to retrieve emails stored on a server and download them to a local device for offline reading. By utilizing POP, users can access their emails directly from their email client, such as Outlook or Thunderbird. One of the key features of POP is that it typically downloads the email messages and may delete them from the server, depending on the settings configured by the user. This is particularly beneficial for users who prefer to manage their emails locally without maintaining an active connection to the internet. Understanding the primary function of POP is essential for individuals who want effective email management and prefer using lightweight clients for handling their correspondence.
