hi

If the exception is unknown source then check for the hostname that you are providing.You can also provide the IP address of the SMTP/POP server instead of the hostname.

some SMTP Server also require authentication.in your code i didn`t find any property for Username & password that is being supplied,so i assume it is not required as you have already signed on to the application.Also check if the SMTP server that you are trying to connect allows connection directly.If it doesnot allow then contact your system admin & ask him to allow requests comming from your machine i.e IP address to access the server.
