- * This module implements all required POP3 server commands as described
- * in RFC1939. It also implements nearly all of the optional commands. The
- * only one missing is APOP, because it implements a "shared secret" method
- * of authentication which currently does not fit well with Citadel. Perhaps
- * we'll do it later.
+ * Current status of standards conformance:
+ *
+ * -> All required POP3 commands described in RFC1939 are implemented.
+ *
+ * -> Nearly all of the optional commands in RFC1939 are also implemented.
+ * The only one missing is APOP, because it implements a "shared secret"
+ * method of authentication which would require some major changes to the
+ * Citadel server core.
+ *
+ * -> The deprecated "LAST" command is included in this implementation, because
+ * there exist mail clients which insist on using it (such as Bynari
+ * TradeMail, and certain versions of Eudora).
