RePOP is a load-balancing proxy server specific to the POP3 protocol. It operates by answering the initial POP3 handshake and authentication request from a POP3 client. RePOP obtains the username from the USER request from the POP3 client, and then looks for the location of the user's home POP3 server in a database. RePOP then initiates a connection to the requested user's home POP3 and reissues the USER request to the POP3 server. A standard proxy connection is connected through the RePOP server directly from the POP3 client to the user's home POP3 server for the remainder of the POP3 session.
