Java在MimeMessage中添加标头

Question

Problem that i'm solving is that when i send mail if the recipient (to mails, cc/bcc) not exist, i don't want sender to get Delivery Status Notification (Failure) mail.

The solution that i'm implementing is adding new header in mail Prevent-NonDelivery-Report

I want to add new header in MimeMessage msg in java

// this is part of the code that defined the mime message 
Session session = Session.getDefaultInstance(props, null);

// we create message
Message msg = new MimeMessage(session);

// this code is not working for me
msg.addHeader("Prevent-NonDelivery-Report", "");

I found the solution i add props.setProperty("mail.smtp.dsn.notify", "NEVER") to the property of the session and that fix my problem
