发送电子邮件phpmailer和javax.mail

Connection failed. Error #2: stream_socket_enable_crypto():
  Peer certificate CN=*.hosting.com' did not match
  expected CN=smtp.anotherhosting.com'

但java代码发送电子邮件没有任何问题,我无法理解为什么. (从任何地方我都看到问题 – how to skip ssl checks with java?

这是代码：

PHP：

<?php
    require './PHPMailer.php';
    require './SMTP.php';

    use PHPMailerPHPMailerPHPMailer;

    $mail = new PHPMailer(true);
    try {
        $mail->SMTPDebug = 4;
        $mail->isSMTP();
        $mail->Host = 'smtp.anotherhosting.com';
        $mail->SMTPAuth = true;
        $mail->Username = 'username@anotherhosting.com';
        $mail->Password = 'password';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;

        //Recipients
        $mail->setFrom('from@company.com');
        $mail->addAddress('myemail@company.com');
        $mail->isHTML(true);
        $mail->Subject = 'Here is the subject12';
        $mail->Body    = 'This is the HTML message bo22dy <b>in bold!</b>';

        $mail->send();
        echo 'Message has been sent';
    } catch (Exception $e) {
        echo 'Message could not be sent. Mailer Error: ',$mail->ErrorInfo;
    }
    try {
        $mail->smtpClose();
    } catch (Exception $e) {
        echo $e->getTraceAsString();
    }

和java：

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class Main {
    public static void main(String[] args) {
        final String username = "username@anotherhosting.com";
        final String password = "password";

        Properties props = new Properties();
        props.put("mail.smtp.auth","true");
        props.put("mail.smtp.starttls.enable","true");
        props.put("mail.smtp.host","smtp.anotherhosting.com");
        props.put("mail.smtp.port","587");

        Session session = Session.getInstance(props,new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username,password);
                    }
                });

        session.setDebug(true);
        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("from@company.com"));
            message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("myemail@company.com"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"
                    + "nn No spam to my email,please!");

            Transport.send(message);

            System.out.println("Done");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

我的任务是使用php代码实现电子邮件发送功能.从我目前的角度来看,由于从一个主机到另一个主机的smtp重定向,它失败了.最有可能的是,phpmailer获取host1,接收重定向到host2,从host2获取证书并将此证书与host1进行比较.同时,java客户端做的一切都很好.如果有人知道如何解决这个问题,请告诉我.

此外,当它试图调用stream_socket_enable_crypto时,PHP代码在line 402失败.
