我正在使用javamail api制作一个自动发送电子邮件java项目。当我使用smtp.gmail.com主机发送此邮件时，它的工作原理。但是当我使用自己的主机服务器mail.sitename.com时...它显示异常..我的用户名和密码是正确的。请有人帮我解决这个问题...... 例外情况是： -

我已经尝试了评论中的所有内容，但没有任何效果。我阅读了很多stackoverflow示例，没有人正确解决它。

得到了解决方案.... 有时javax.mail.AuthenticationFailedException：535身份验证失败（＃5.7.1）发生在主机未使用代码对用户进行身份验证时...因为我呼叫主机将邮件发送给在一个程序运行时审批500个用户。所以sendMail（）调用500次并让服务器挂起。因此它阻止我的编码站点的身份验证，但可以使用浏览器访问。 当我创建一个新帐户时，我想出了解决方案，然后在编码中我创建了一个线程，通过该线程，10秒间隔将调用sendMail（），然后一次性发送给100个用户。主机来自网络解决方案电子邮件登录。 希望我能给别人解决这类问题的方法。 ：）

在我需要发送包含可以在不同客户端计算机上生成的测试结果的附件的电子邮件的项目中，我使用了以下属性和代码（这些属性被转换为提到的Settings对象中的字段在下面的代码中）
==================== Properties Section ====================
! Default Properties for the Email section of the project - others omitted
! The email provider may or may not require authentication - make sure to make the appropriate choices on the client
EmailSender = aUser@gmail.com
EmailPassword = unEncriptedPassword
EmailRecipients = me@gmail.com,she@gmail.com,you@yahoo.com,andAnyBodyElse@aol.com
EmailHost = smtp.gmail.com
EmailPort = 587
EmailAuthenticationRequired = true
==================== Code Section ====================
public class Email {
public static void sendMail(String subject, String messageBody, String fileName) throws MessagingException {
DDTSettings settings = DDTSettings.Settings();
final String sender = settings.emailSender();
final String password = settings.emailPassword();
String[] recipients = settings.emailRecipients().split(",");
String host = settings.emailHost();
String port = settings.emailPort();
boolean emailAuthenticationRequired = settings.emailAuthenticationRequired();
String trueOrFalse = emailAuthenticationRequired ? "true" : "false";
Properties properties = System.getProperties();
Session session;
// Use system properties and add some related to email protocol
Properties props = System.getProperties();
// Setup mail server
props.setProperty("mail.smtp.host", host);
props.setProperty("mail.smtp.port", port);
props.setProperty("mail.smtp.ssl.enable", "false");
props.setProperty("java.net.preferIPv4Stack","true");
props.setProperty("mail.smtp.starttls.enable", trueOrFalse);
props.setProperty("mail.smtp.auth", trueOrFalse);
// Create a session with or without authentication object as indicated in the settings.
if (emailAuthenticationRequired) {
Authenticator auth = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(sender, password);
}
};
session = Session.getDefaultInstance(props, auth);
}
else {
props.setProperty("mail.smtp.user", sender); // Needed if not authenticating
props.setProperty("mail.smtp.password", password); // Needed if not authenticatin
session = Session.getDefaultInstance(props);
}
// Setup the message in two parts, body and attachment then send it
try{
// Create a default MimeMessage object.
MimeMessage message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(sender));
//message.setReplyTo({new InternetAddress(sender)});
// Set recipients
for (int i = 0; i<recipients.length; i++) {
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(recipients[i]));
}
// Set Subject: header field
message.setSubject(subject);
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Set the body of the message as html content
messageBodyPart.setContent(messageBody, "text/html");
// Create a multipart message
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(fileName);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(source.getName());
multipart.addBodyPart(messageBodyPart);
// Place the entire kit & caboodle in the message
message.setContent(multipart );
// Send message
Transport.send(message);
}
catch (MessagingException e) {
e.printStackTrace();
}
}
}

如果您将Gmail帐户用于电子邮件（SMTP），请确保在application.properties文件中具有正确的电子邮件密码，并启用此设置 为您的gmail帐户允许安全性较低的应用。
