Java mail SMTP server

[swapnil dey]

Hi folks!
i have a problem sending mail using JavaMail API. i don't know which eMail server to use, im using Win2000 box with IIS installed, but when i try sending mail using this mail server i get the exception :

message errorjavax.mail.SendFailedException: 
Sending failed;  nested exception is:        
javax.mail.SendFailedException: Invalid 
Addresses;  nested exception is:        
javax.mail.SendFailedException: 550 Unable to 
relay for [e-mail];  nested 
exception is:        
javax.mail.SendFailedException: 550 Unable to 
relay for [e-mail]

i also tried sending & reading mail thru the hclinfinet SMTP server (using the ip addresses of the SMTP & POP3 servers) but i got the exception:

message errorjavax.mail.SendFailedException: 
Sending failed;  nested exception is:        
javax.mail.MessagingException: Could not connect

it seems the problem is in getting access to the specified server which should not happen as i am a registered user of hclinfinet.
Could u help in sorting out the prob...
Thanx in advance.
