Explanation: The Post Office Protocol version 3 (POP3) is an application layer protocol designed to enable email clients to retrieve messages from a mail server. According to the sources, the default operation of POP3 is to download the email to the client's local application and then delete it from the server. This service operates over TCP port 110 and is specifically intended for message retrieval, distinguishing it from SMTP, which is used for sending mail, and IMAP, which typically maintains messages on the server.
