Detailed explanation-1: -POP3 is an older protocol that was originally designed to be used on only one computer. Unlike modern protocols that use two-way synchronization, POP3 only supports one-way email synchronization, only allowing users to download emails from a server to a client.
Detailed explanation-2: -POP3 and IMAP are handling the incoming emails and they operate in different ways to retrieve or access your email messages. Thus, they are considered mail access protocols. On the other hand, the Simple Mail Transfer Protocol is behind the message transfer from server to server, or mail client to server.
Detailed explanation-3: -The common protocols for email delivery are Post Office Protocol (POP), Internet Message Access Protocol (IMAP), and Simple Mail Transfer Protocol (SMTP).
Detailed explanation-4: -In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. POP version 3 (POP3) is the version in common use, and along with IMAP the most common protocols for email retrieval.
