FTP returns 150 instead of code/message for "port is disabled"
--------------------------------------------------------------

                 Key: FTPSERVER-110
                 URL: https://issues.apache.org/jira/browse/FTPSERVER-110
             Project: FtpServer
          Issue Type: Bug
          Components: Core
            Reporter: Rico Neubauer


If using pasive mode and active mode is disabled the "PORT" command is answered 
with "510 port is disabled".
However if you go on with the next command ("LIST"), then the FTPServer answers 
"150 ..." instead of "510 PORT command disabled before LIST") or
some similiar descriptive error. Also the it is tried to open the active port 
and a 425 is sent:
