当我使用Java邮件验证时，我在从Java发送电子邮件时遇到问题。我无法弄清楚我得到以下异常：
javax.mail.AuthenticationFailedException: 530 Access denied
我将在整个代码下面显示。你能告诉我我做错了什么吗？ 请注意，在添加身份验证之前一切正常。 另外，你知道是否可以在两个不同的域之间发送电子邮件（例如gmail到yahoo）？

这是我用来通过我的Gmail帐户在我的JSP学术项目中发送电子邮件的代码：
package my_util;
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class Mail
{
private String d_email = "myemailid@gmail.com",
d_password = "mypassword",
d_host = "smtp.gmail.com",
d_port = "465";
public boolean sendMail(String strTo, String strSubject, String strBody){
Properties props = new Properties();
props.put("mail.smtp.user", d_email);
props.put("mail.smtp.host", d_host);
props.put("mail.smtp.port", d_port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
try
{
Session session = Session.getDefaultInstance(props, null);
MimeMessage msg = new MimeMessage(session);
msg.setText(strBody);
msg.setSubject(strSubject);
msg.setFrom(new InternetAddress(d_email));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(strTo));
msg.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(d_host, d_email, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
return true;
}
catch (Exception mex)
{
mex.printStackTrace();
return false;
}
}
}
我希望它可以帮到你。 ：）
