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来发送电子邮件。
要测试垃圾邮件，我使用的是mail-tester.com网站。该网站告诉我，该电子邮件被标记为垃圾邮件，其下方为负阈值：
-3.603 HELO_LOCALHOST HELO_LOCALHOST
我根据网站发现了helo和ehlo参数。要覆盖helo和ehlo，我使用了“mail.smtp.localhost”属性。但我能够改变ehlo，但我无法改变他的价值。
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

感谢任何帮助。

您是否正在使用JavaMail将消息发送到Apache James服务器，然后将其发送到mail-tester.com？如果是这样，那么您需要担心的是Apache James配置，而不是JavaMail配置。请注意，在单个SMTP会话中只使用HELO或EHLO中的一个。
看起来你的Apache James服务器在与mail-tester.com交谈时正在使用HELO，并且没有使用服务器的完整DNS名称正确识别自己。确保您的服务器具有 DNS名称（而不仅仅是DHCP获取的IP地址），并且服务器上的名称服务已正确配置为知道服务器的DNS名称。

可能是因为来自地址的域名为admin@xxxxxxxx.com 这不会解析为任何特定的已知主机。删除后尝试。如果您的邮件仍标记为垃圾邮件，则必须知道在接收方端应用的过滤器。
