re:CRM email router with POP3

 Hi,this is Prasad,

              I am trying to configure CRM4.0 Email router With POP3.We have an external pop3 and smtp based Email
service.

             In email router configuation Manager,while we are testing the access we are getting these Error

 ""Incoming Status: Failure - An error occurred while executing POP3 command "<Command removed for security reasons>". The server response was: "-ERR authorization first".   ""

   Anybody having any idea about this error,I  gone through the CRM Official guides and also other guides,but no use.Please reply anybody,having any idea about it.

Thanks&Regards
