I have put "mail.smtp.auth" properties "true" in my program.
I am using IIS4 's SMTP server to send email.
I can send email successfully, when I disable the authentication.
Here are my debug messages:
DEBUG SMTP: Attempt to authenticate
DEBUG SMTP SENT: AUTH LOGIN
DEBUG SMTP RCVD: 334 VXNlcm5hbWU6

DEBUG SMTP SENT: dHNhbmdfY3M=
DEBUG SMTP RCVD: 334 UGFzc3dvcmQ6

DEBUG SMTP SENT: YWJjMTIz
DEBUG SMTP RCVD: 235 Authentication successful


DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]
DEBUG SMTP: useEhlo true, useAuth true

It shows everything ok, however, I got the following exception from my application:
javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.AuthenticationFailedException

Would you tell me why?
