What is POP3 Mail Protocol?

POP3 allows e-mails to be retrieved from an E-mail server. When you download an e-mail with POP3, e-mails are stored locally because the e-mail is deleted from the server.

If you access your account from multiple locations using the POP3 protocol, you will not be able to see the e-mails you received earlier. The messages you download are stored on one device only.

Due to the high storage requirements of POP3 is not recommended for small businesses. The POP3 mail protocol is usually a useful protocol for ISPs.

The SMTP protocol is used when the user sends a new E-mail. Additionally, the connection between the e-mail servers is controlled by SMTP. When a user wants to read the newly received e-mail, he / she will be able to read the e-mail via POP3 or IMAP protocols. As a result, POP3 is an E-mail receive protocol.

POP3 uses TCP port 110 by default. The TCP 995 port can also be used for e-mail security. Also, POP3 is defined in RFC 1939.

How POP3 Works?

The answer to the question of how POP3 works: the received emails are deleted from the server and stored on the device that is logged into the account. As a result, when you access your account elsewhere, you will not be able to see the e-mails you received earlier.
