Hi,
In my web page, user sends email with attachment, so upload is related. I
load the file in a byte array, and try to send with JavaMail(I know there is
Mail api in Tomcat-Common. But I have no a good example).
The related code is copied at the end.
The email serve needs no user-name and password, because the C++ program
sends email without authentication.
if I set prop.put("mail.smtp.auth", "false");
Exception: SendEmail Error: javax.mail.AuthenticationFailedException
If I set to Password and username to "", or set the user name to the
From-Email address:
SendEmail Error: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0
Authentication required
Please tell me what's wrong. Thanks.
