【问题描述】：

想处理发送邮件时 smtp 主机服务器重启的情况。发送脚本的电子邮件不应因运行时错误而终止。它应该尝试重新连接到服务器主机并再次发送电子邮件

我的代码：

$config=array('protocol'=>'smtp',
                'smtp_host'=>'example.com',     
                'smtp_port'=>587,
                'smtp_user'=>'******',
                'smtp_pass'=>'***', 
                'priority'=> 1,
                'smtp_timeout'=>'30',
                //'smtp_keepalive'=>TRUE,
                'mailtype'  => 'html',              
                'charset'=>'utf-8',
                'wordwrap'=>True);  
 foreach($res2 as $email)
{
  $this->email->from($fromemail,$fromname);
                
                $this->email->to($email);              
                $this->email->subject('Dummy Email');               
                $body=$emailDesign2;
                $this->email->message($body);
                
                
                
                
                                
                    if($this->email->send())
                    {
                        echo "Mail Sent<br/>";
                        $total++;
                    }
                    else
                    {
                         echo "Mail Not Sent";
                    }

}

尝试创建一个函数，当发送失败时再次调用该函数。

function send_email($class, $details){

    $total = 0;

    $class->from($details['fromemail'], $details['fromname']);
                
    $class->to($details['email']);              
    $class->subject('Dummy Email');               
    $body = $datails['body'];
    $class->message($body);
                
    if($class->send()) {
        echo "Mail Sent<br/>";
        $total++;
    } else {
       send_email($class, $details);
    }

    return $total;
}

foreach($res2 as $email) {
    // Return the number of success emails
    $total = send_email($this->email, array(
        'email' => $email,
        'fromemail' => $fromemail,
        'fromname' => $fromname,
        'body' => $emailDesign2
    ));
}
