What is the commonly used version of POP?

Explanation:
POP3 is the commonly used version. It’s the third version of the Post Office Protocol and is defined in standards like RFC 1939. This version matured to become the widely supported and implemented method for retrieving email from a server. Earlier versions (POP1 and POP2) are obsolete today, and there isn’t a standard called POP4. POP3 provides a simple, reliable way to download messages (with the option to leave or delete them on the server), which is why it remains the go-to choice in many systems. In practice, many environments also use IMAP for more advanced server-side management, but among POP options, POP3 is the prevalent one.
