Understanding the POP3 service
The POP3 service is an e-mail service that retrieves e-mail. Administrators can use the POP3 service to store and manage e-mail accounts on the mail server.
When the POP3 service is installed on the mail server, users can connect to the mail server and retrieve and download e-mail to their local computer. They do so by using an e-mail client that supports the POP3 protocol (such as Microsoft Outlook). The POP3 service is used with the Simple Mail Transfer Protocol (SMTP) service, which sends outgoing e-mail.
