     27  * <li>If this command was not preceded by a valid RNFR command, then reply with 503</li>
     28  * <li>If the required TO pathname parameter is missing, then reply with 501</li>
     29  * <li>If the TO pathname parameter does not specify a valid filename, then reply with 553</li>
     30  * <li>If the TO pathname parameter specifies an existing directory, then reply with 553</li>
     31  * <li>If the current user does not have write access to the parent directory, then reply with 553</li>
     32  * <li>Otherwise, rename the file, remove the FROM path stored in the session by the RNFR command, and reply with 250</li>
     33  * </ol>
     34  * The supplied pathname may be absolute or relative to the current directory.
