我觉得你这里有问题。你认证是空的。
Authenticator auth = new SMTPAuthenticator();
尝试
Authenticator auth = new Authenticator()
{
@Override
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(SMTP_AUTH_USER, SMTP_AUTH_PWD);
}
};
此代码适用于我。 javax.mail v1.5
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Main {
public static void main(String[] args) {
final String smtpAuthUserName = "YOUR_ADDRES@YOURCOMPANY.COM";
final String smtpAuthPassword = "YOUR_PASSWORD";
String emailFrom = "EMAIL_FROM";
String emailTo = "EMAIL_TO";
Authenticator authenticator = new Authenticator()
{
@Override
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(smtpAuthUserName, smtpAuthPassword);
}
};
Properties properties = new Properties();
properties.setProperty("mail.smtp.host", "smtp.office365.com");
properties.setProperty("mail.smtp.port", "587");
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.starttls.enable", "true");
Session session = Session.getInstance( properties, authenticator );
try
{
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(emailFrom));
InternetAddress[] to = {new InternetAddress(emailTo)};
message.setRecipients(Message.RecipientType.TO, to);
message.setSubject("PLACE_SUBJECT_HERE");
message.setText("YOUR_MESSAGE_HERE");
Transport.send(message);
}
catch (MessagingException exception)
{
exception.printStackTrace();
}
}
}

如果在添加上述代码后错误仍然存在。请参阅项目的mail.jar。可能是该项目的mail.jar已损坏。使用最新版本的mail.jar更改它并检查< / p>
答案 2 :(得分：0)
使用较旧版本的 javax.mail （1.3.1）时出现此错误。当我切换到更高版本（1.4.4）时，问题就消失了。
如果您正在使用Eclipse，则可能需要在构建路径中查找项目正在使用的库，而不仅仅是您指定的外部库，还有内置的JavaEE5等可能具有的库。其中的这个库的旧版本。
您可以在代码中查看此语句上调试所使用的库的确切版本：Session session = Session.getInstance(...
它不会向您显示源代码，但会为您提供它正在使用的mail.jar的目录路径，您可以打开它以查看版本（在 MANIFEST中文件）。
