【问题描述】:
我正在尝试从我的 Java 应用程序向任何特定的电子邮件地址发送一封电子邮件。 我正在使用 Java Mail API,但不幸的是我收到了 SMTPSendFailedException 错误。任何人都可以告诉我我在哪里做错了。这是我的代码
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
//import SeconMail.Authenticator;
public class SendMail
{
public static void main(String [] args)
{
// Recipient's email ID needs to be mentioned.
String to = "to@gmail.com";
// Sender's email ID needs to be mentioned
String from = "from@expertflow.com";
// Assuming you are sending email from localhost
String host = "smtp.gmail.com";
// Get system properties
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.auth", "false");
// Get the default Session object.
Session session = Session.getDefaultInstance(properties);
session.setDebug(true);
try{
// Create a default MimeMessage object.
MimeMessage message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
// Set Subject: header field
message.setSubject("This is the Subject Line!");
// Now set the actual message
message.setText("This is actual message");
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
}catch (MessagingException mex) {
mex.printStackTrace();
}
}
}

试试
properties.put("mail.smtp.auth", "true");,你可能还需要用户名和密码。 -
