从 JamesServer 发送的电子邮件被标记为垃圾邮件。我正在使用 JavaMail 连接到 JamesServer 以发送电子邮件。
为了测试垃圾邮件，我使用了 mail-tester.com 站点。该站点告诉我该电子邮件被标记为垃圾邮件，其阈值为以下：
-3.603 HELO_LOCALHOST HELO_LOCALHOST
我遇到了基于站点的 helo 和 ehlo 参数。为了覆盖 helo 和 ehlo，我使用了“mail.smtp.localhost”属性。但是我能够更改 ehlo 但我无法更改 helo 值。
如何更改 helo 参数的值？
这是我的java示例代码：
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.Date;
import java.util.Properties;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class TestSendMail {
private String fromEmail = "admin@xxxxxxxxxx.com";
public void sendmail() {
Properties properties = new Properties();
final String smtpHost = "xxxxxxxxxx.com";
String port = "25";
String strHostName = smtpHost;
try {
strHostName = InetAddress.getLocalHost().getHostName();
System.out.println(strHostName);
} catch (UnknownHostException e) {
}
properties.put("helo", strHostName );
properties.put("mail.host", strHostName );
properties.put("mail.smtp.localhost", strHostName );
properties.put("mail.smtps.localhost", strHostName);
properties.put("mail.smtp.host", smtpHost);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.transport.protocol", "smtp");
Session session = Session.getInstance(properties,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(fromEmail,"Welcome123!");
}
});
String toEmail = "web-3a2Lxc@mail-tester.com";
String replyTo = "noreply@" + smtpHost;
String messageBody = "<html><body>Test body</body></html>";
try {
MimeMessage message = new MimeMessage(session);
message.setSentDate(new Date());
message.setFrom(new InternetAddress(fromEmail));
message.addRecipient(javax.mail.Message.RecipientType.TO, new InternetAddress(toEmail));
message.setSubject("Test");
message.setReplyTo(new javax.mail.Address[]
{
new InternetAddress(replyTo)
});
message.setContent(messageBody, "text/html");
Transport.send(message);
System.out.println("Message sent successfully....");
} catch (MessagingException mex) {
mex.printStackTrace();
System.out.println(mex.getMessage());
}
}
public static void main(String[] args) {
TestSendMail send = new TestSendMail();
send.sendmail();
}
}
这是我从 mail-tester.com 获得的电子邮件日志
