i have a free proxy server software on my proxy server(A) which sends mail through a particular mail server( for all the computers attached to A successfully but when i give the same address in my java mail code it gives me the following of the errors. any ideas why?
1.> this is on my local development environment where i am sending this through one of my computers connected to proxy.

javax.servlet.ServletException: Sending failed;
nested exception is:
javax.mail.MessagingException: Unknown SMTP host:

2.> this is the error i get when i try to send mail through the proxy server who is hosting the site(i mean the server it self)
javax.servlet.ServletException: Sending failed;
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)

Please guide me .it is urgent. thnx in advance.

I'm assuming your proxy is configured to relay SMTP? Most only handle HTTP.

Your second error is a 553 error - which means the mailbox name is not allowed. This is expected to be because the mailbox syntax is incorrect, but can also happen if the server is configured to restrict the domains you can send mail to.

For both errors I'd check the proxy configuration.
