Java Mail不发送电子邮件

我使用javax.mail-api 1.5.3发送电子邮件。这是我的电子邮件发送代码:

    Properties properties = System.getProperties();
    properties.setProperty("mail.smtp.host", host);
    properties.setProperty("mail.smtp.port", port);
    properties.setProperty("mail.user", user);
    properties.setProperty("mail.password", password);
    properties.setProperty("mail.debug", "true");
    Session mailSession = Session.getDefaultInstance(properties);
    MimeMessage mimeMessage = new MimeMessage(mailSession);
    mimeMessage.setHeader("Content-Type", "text/html; charset=UTF-8");
    mimeMessage.setFrom(new InternetAddress(from));
    mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    mimeMessage.setSubject(subject, "UTF-8");
    mimeMessage.setContent(body, "text/html; charset=UTF-8");
    Transport.send(mimeMessage);

但是此代码会导致以下错误。

调试输出:

这是奇怪的日志,目的地电子邮件有效,但此日志显示目的地地址无效!!!!

DEBUG SMTP: Sending failed because of invalid destination addresses

注意:所有电子邮件和ips都会针对此问题进行有意更改,并且它们是正确的。

提前感谢您的关注。

答案 0 :(得分:3)

 550 5.7.1 Unable to relay

这说明:地址很好,但不允许从您提供的MAIL FROM:发送电子邮件到SMTP命令中指定的RCPT TO:

在发送电子邮件之前,SMTP服务器很可能希望您登录(使用SMTP AUTH)。

为了做到这一点,你可以试试这个:

Transport.send(mimeMessage, username, password);

如果无法设置正确的SMTP AUTH:

props.put("mail.smtp.auth", "true");
Session mailSession = Session.getDefaultInstance(properties, new Authenticator() {
    public PasswordAuthentication getPasswordAuthentication() {
       //Fill in your data here.
       return new PasswordAuthentication("user", "password");
    }
});
