+The \fIpopd\fR server implements the Post Office Protocol (version 3),
+as described in RFC1081 and RFC1082.
+Basically, the server listens on the TCP port named \*(lqpop\*(rq
+for connections and enters the
+POP upon establishing a connection.
+The `\-p' option overrides the default TCP port.
+.PP
+If the POP2 configuration option is defined,
+then the server also implements version 2 of the protocol.
+.PP
+If the APOP configuration option is defined,
+then the server supports a non-standard mechanism for identity-establishment
+in which authentication credentials are used to provide for origin
+authentication and reply protection,
+but which do not involve sending a password in the clear over the network.
+See \fIpopauth\fR(8) for more details.

+For historical reasons, the \fIMH\fP POP defaults to using
+the port named \*(lqpop\*(rq (109) instead of its newly assigned
+port named \*(lqpop3\*(rq (110).
+See the POPSERVICE configuration option for more details.

+Previous versions of the server (10/28/84) had the restriction that
+the POP client may retrieve messages for login users only.
+This restriction has been lifted,
+and true POB support is available
+(sending mail to a mailbox on the POP service host
+which does not map to a user\-id in the password file).
