mantis 使用 465端口后，无法发送邮件

mantis使用PHPMailer编写发送邮箱的代码

PHPMailer需PHP的socket扩展支持，而PHPMailer链接qq域名邮箱时需要ssl加密方式，固php还得openssl的支持，可以查看phpinfo，如下两项均存在则可以使用
以下得php脚本可以测试mail得错误原因,我这边的报错是

2018-12-26 05:37:50     Connection: opening to ssl://smtp.123.com:465, timeout=300, options=array ( )
2018-12-26 05:37:50     Connection failed. Error #2: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:
                                          error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed [/usr/local/httpd-2.4.27/htdocs/mantisbt/vendor/phpmailer/phpmailer/class.smtp.php line 294]

2018-12-26 05:37:50     SMTP ERROR: Failed to connect to server:  (0)

加上了忽略证书错误后，可以正常发送

<?php

header("Content-Type:text/html;charset=utf-8");


require 'PHPMailerAutoload.php'; // 脚本要跟PHPMailerAutolad.php放在同一目录

// debug 等级
$mail = new PHPMailer;

//   -----------------
//   这个配置应该是不验证证书

$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);

// --------------------

$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.123.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '123@123.com';                 // SMTP username
$mail->Password = '123';                           // SMTP password
$mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465;                                    // TCP port to connect to




$mail->setFrom('123@123.com', 'Mailer');
$mail->addAddress('123@123.com', 'Joe User');     // Add a recipient
$mail->addReplyTo('123@123.com', 'Information');
$mail->addCC('123@123.com');

$mail->addAttachment('/etc/fstab', 'fstab');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

?>

在mantis得core/email_api.php中
$t_mail->IsHTML( false );              # set email format to plain text  
得上面加上
$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);
后正常发送邮件
