客户端未经过身份验证,无法在MAIL FROM期间发送匿名邮件

我正在尝试在调用此方法的java应用程序中发送电子邮件:

File::makeDirectory(public_path('storage/uploads/albums/'.$name));

但由于某些原因,当调试遇到Transport.send()时,我遇到了这个异常:

public static void sendEmail() {

    // Create object of Property file
    Properties props = new Properties();

    // this will set host of server- you can change based on your requirement 
    props.put("mail.smtp.host", "smtp.office365.com");

    // set the port of socket factory 
    //props.put("mail.smtp.socketFactory.port", "587");

    // set socket factory
    //props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");

    // set the authentication to true
    props.put("mail.smtp.auth", "true");

    // set the port of SMTP server
    props.put("mail.smtp.port", "587");

    // This will handle the complete authentication
    Session session = Session.getDefaultInstance(props,

            new javax.mail.Authenticator() {

                protected PasswordAuthentication getPasswordAuthentication() {

                return new PasswordAuthentication("xx@mail.com", "xx");


                }

            });

    try {

        // Create object of MimeMessage class
        Message message = new MimeMessage(session);

        // Set the from address
        message.setFrom(new InternetAddress("xx@mail.com"));

        // Set the recipient address
        message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("yy@mail.com"));

                    // Add the subject link
        message.setSubject("Testing Subject");

        // Create object to add multimedia type content
        BodyPart messageBodyPart1 = new MimeBodyPart();

        // Set the body of email
        messageBodyPart1.setText("This is message body");

        // Create object of MimeMultipart class
        Multipart multipart = new MimeMultipart();

        // add body part 2
        multipart.addBodyPart(messageBodyPart1);

        // set the content
        message.setContent(multipart);

        // finally send the email
        Transport.send(message);

        System.out.println("=====Email Sent=====");

    } catch (MessagingException e) {

        throw new RuntimeException(e);

    }

}

为什么即使我使用了Authenticator()?

也会发生这种情况

答案 0 :(得分:2)

如果通过端口587连接,则最初启动普通连接,必须通过显式发送STARTTLS命令启动TLS。您必须告诉JavaMail这样做,否则它将尝试进行不安全的操作。除非建立了TLS连接,否则SMTP服务器不会发送任何身份验证机制信息,因此JavaMail假定不需要身份验证并尝试不发送邮件。

将以下条目添加到属性中:

props.put("mail.smtp.starttls.enable", "true");

在尝试进行身份验证之前,JavaMail应该尝试切换到TLS。

如果失败,您需要通过设置属性

启用调试
props.put("mail.debug", "true");a

并在此处发布输出。
