Detailed explanation-1: -POP3 (Post Office Protocol 3) is the email retrieval protocol used to receive emails from the server. POP3 downloads the original emails from the email server on a single device/computer. Then it deletes the emails from the server’s inbox. It lacks synchronization; thus, several devices cannot access the same email.
Detailed explanation-2: -On the other hand, POP3 downloads your emails to your local computer, deleting them from the server. Thus, it reduces the space your email account uses on your web server.
Detailed explanation-3: -The post office protocol (POP) is the most commonly used message request protocol in the Internet world for transferring messages from an e-mail server to an e-mail client. With POP3, the e-mail client requests new messages from the e-mail server, and the server “pops” all new messages out to the client.
