Question

这是我的内部电子邮件类，它使用PHP mail（）来发送电子邮件：

class Email {

    public $from = '';
    public $from_name = '';
    public $reply_to = '';
    private $to = '';
    private $subject = '';
    private $message = '';
    private $attachment = '';
    private $attachment_filename = '';

    public function __construct($to, $subject, $message, $attachment = '', $attachment_filename = '') {
        $this -> to = $to;
        $this -> subject = $subject;
        $this -> message = $message;
        $this -> attachment = $attachment;
        $this -> attachment_filename = $attachment_filename;

        $this -> from = SITE_EMAIL;
        $this -> from_name = SITE_NAME_URL;
        $this -> reply_to = SITE_EMAIL;
    }

    public function mail() {

        if (!empty($this -> attachment)) {
            $filename = empty($this -> attachment_filename) ? basename($this -> attachment) : $this -> attachment_filename ;
            $path = dirname($this -> attachment);
            $mailto = $this -> to;
            $from_mail = $this -> from;
            $from_name = $this -> from_name;
            $replyto = $this -> reply_to;
            $subject = $this -> subject;
            $message = $this -> message;

            $file = $path.'/'.$filename;
            $file_size = filesize($file);
            $handle = fopen($file, "r");
            $content = fread($handle, $file_size);
            fclose($handle);
            $content = chunk_split(base64_encode($content));
            $uid = md5(uniqid(time()));
            $name = basename($file);
            $header = "From: ".$from_name." <".$from_mail.">\r\n";
            $header .= "Reply-To: ".$replyto."\r\n";
            $header .= "MIME-Version: 1.0\r\n";
            $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
            $header .= "This is a multi-part message in MIME format.\r\n";
            $header .= "--".$uid."\r\n";
            $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
            $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
            $header .= $message."\r\n\r\n";
            $header .= "--".$uid."\r\n";
            $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use diff. tyoes here 
            $header .= "Content-Transfer-Encoding: base64\r\n";
            $header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
            $header .= $content."\r\n\r\n";
            $header .= "--".$uid."--";
            if (mail($mailto, $subject, "", $header, '-f'.$this -> from)) {
                return true;
            } else {
                return false;
            }
        } else {
            $header = "From: ".($this -> from_name)." <".($this -> from).">\r\n";
            $header .= "Reply-To: ".($this -> reply_to);
            if (mail($this -> to, $this -> subject, $this -> message, $header, '-f'.$this -> from)) {
                return true;
            } else {
                return false;
            }
        }

    }   

}

每次用户完成订单并通过PayPal支付IPN状态=“已完成”时，IPN会通知我的网站并触发此功能：

function emailBuyerAdminCompleted($ipn_data, $validItemsText, $password) {
    $message = "Hi, {$ipn_data['first_name']},

PayPal transaction details
-------------------------------
Buyer name: {$ipn_data['first_name']} {$ipn_data['last_name']}
Transaction ID: {$ipn_data['txn_id']}
Payment gross: {$ipn_data['mc_gross']}
Payment currency: {$ipn_data['mc_currency']}
Payment date: {$ipn_data['payment_date']}
Number of items: {$ipn_data['num_cart_items']}

Product(s) purchased
-------------------------------
$validItemsText
Authentication credentials
-------------------------------
User Name: {$ipn_data['payer_email']}
Password: $password



Regards,
".SITE_NAME." Team
".SITE_URL."/";
    $buyerEmail = new Email($ipn_data['payer_email'], 'Product(s) Download Credentials - $'.$ipn_data['mc_gross'].' - '.SITE_NAME_URL, $message);
    $buyerEmail -> mail();
    $adminEmail = new Email(SITE_EMAIL, 'Product(s) Download Credentials - $'.$ipn_data['mc_gross'].' - '.SITE_NAME_URL, $message);
    $adminEmail -> mail();
}

您可以看到我正在向 SITE_EMAIL （info@example.com）发送2封同一邮件正文的电子邮件（$ buyerEmail和$ adminEmail），这是我的电子邮件和 $ ipn_data ['payer_email'] 这是买家的PayPal电子邮件。

我的SITE_EMAIL（info@example.com）是在Google Apps上托管的电子邮件，它始终会收到此消息。当我点击邮件标题详细信息时，它正确邮寄并签名我的网站example.com：http://postimg.org/image/jaow7tpwx/

然而，大约30％ - 50％的客户抱怨在付款后没有收到消息，我必须手动将相同的消息（我收到的）转发给他们。这令人沮丧，因为：

我无法轻松调试错误，因为我无法访问他们的电子邮件帐户。
一些厌倦了等待我的回复时间的客户只是在我查看我的电子邮件并手动将消息发送给他们之前撤回了他们的钱。经济损失。

我试着问他们这件事。有些人说他们在垃圾邮件文件夹中找到了这封邮件（我认为邮件正确邮寄并且签名邮件永远不会在那里结束！）有些人说他们从未在任何地方找到它，即使是在付款数天之后。

知道这里有什么不对吗？

或者有没有比PHP mail（）更好的方法？这会有更高的交付率？我最好使用第三方服务还是SMTP？

此处保证交付和不识别垃圾邮件的最佳做法是什么？

使用PHP mail()时遇到问题，而某些消息未送达。我猜测使用mail()时标题并不完美。我发现问题的唯一方法是将PHP Pear Mail库安装到服务器上，并使用SMTP和PEAR发送电子邮件。

您需要包含其他标题，而不仅仅是以下内容。这只是一个如何使用PEAR和smtp发送电子邮件的简单示例。

require_once "Mail.php";

$from = "Your Name <your@email.com>";
$to = 'to@email.com';
$subject = "Some Subject";
$body = "Some Message";

$host = "smtp.yourhost.com";  
$port = "25";

$headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
$smtp = Mail::factory('smtp',
   array ('host' => $host,
     'port' => $port,
     'auth' => false));

$mail = $smtp->send($to, $headers, $body);

注意：您还可以通过定义用户名＆amp;来进行身份验证的smtp。密码和设置auth => true

用户/客户未收到PHP mail（）消息？
