PHP Mailer 需要 30 多秒来发送欢迎电子邮件

Question

所以我使用 PHP 中的 PHPMailer 库在我的用户注册时发送一封欢迎电子邮件，而这需要很长时间。

点击注册后，实际加载主页大约需要 30 - 50 秒。它基本上使页面处于重新加载状态超过 30 秒。

我使用的代码如下...

if ($config['user']['welcome_email_enabled'])
    $autoLoader->getLibrary('mail')->sendWelcomeEmail($email, $username);

我的邮件库就在这里。

<?php
/**

 *
 * @info         Handles the mail functions.
 * @author       Liam Digital <liamatzubbo@outlook.com>
 * @version      1.0 BETA
 * @package      MangoCMS_Master
 *
 */

defined("CAN_VIEW") or die('You do not have permission to view this file.');

class mangoMail {
    private $phpMailer;

    public function assignMailer($phpMailer) {
        $this->phpMailer = $phpMailer;
    }

    public function setupMail($username, $password, $eHost) {
        if ($this->phpMailer == null)
            return;

        $this->phpMailer->isSMTP();
        $this->phpMailer->Host = $eHost;
        $this->phpMailer->SMTPAuth = true;
        $this->phpMailer->Username = $username;
        $this->phpMailer->Password = $password;
        $this->phpMailer->SMTPSecure = 'tls';
        $this->phpMailer->Port = 587;
    }

    public function sendMail() {
        if ($this->phpMailer == null)
            return;

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

    public function setFrom($from, $fromTitle) {
        $this->phpMailer->setFrom($from, $fromTitle);
    }

    public function addAddress($address) {
        $this->phpMailer->addAddress($address);
    }

    public function setSubject($subject) {
        $this->phpMailer->Subject = $subject;
    }

    public function setBody($body) {
        $this->phpMailer->Body = $body;
    }

    public function setAltBody($altBody) {
        $this->phpMailer->AltBody = $altBody;
    }

    public function setHTML($html) {
        $this->phpMailer->isHTML($html);
    }

    public function addReply($email, $name = '') {
        $this->phpMailer->addReplyTo($email, $name);
    }

    public function sendWelcomeEmail($email, $username) {
        global $config;
        $mailer = $this->phpMailer;
        $mailer->setFrom($config['website']['email'], $config['website']['owner']);
        $mailer->addAddress($email, $username);
        $mailer->addReplyTo($config['website']['email'], 'Reply Here');
        $mailer->isHTML(true);
        $mailer->Subject = 'Welcome to ' . $config['website']['name'] . ' (' . $config['website']['link'] . ')';
        $mailer->Body = '<div style="background-color:#1a8cff;padding:24px;color:#fff;border-radius:3px;">
        <h2>Welcome to Zubbo ' . $username . '!</h2>Thank you for joining the Zubbo community, we offer spectacular events, opportunities, and entertainment.<br><br>When you join Zubbo you will recieve <b>250,000 credits</b>, <b>100,000 duckets</b>, and <b>5 diamonds</b>.

        </div>';
        $mailer->AltBody = 'Here is a alt body...';
        if (!$mailer->send()) {
            exit('FAILED TO SEND WELCOME EMAIL!! ' . $mailer->ErrorInfo);
        }
    }
}
?>

所以我首先调用这些，然后在我想实际发送电子邮件时调用 sendWelcomeEmail()。

$mailer->assignMailer(new PHPMailer());

和

$mailer->setupMail(
    "********@gmail.com",
    "**************",
    "smtp.gmail.com");

为什么要花这么长时间？是不是要花这么长时间..

Answer 1

在页面提交期间使用远程 SMTP 并不是一个真正的好东西 - 正如您所见，它通常非常慢（有时是故意的，用于 greetdelay 检查）。解决它的方法是始终提交到本地（快速）邮件服务器并让它处理等待，并处理您无法从 PHPMailer 处理的延迟交付之类的事情。您还需要在走这条路线时正确处理反弹，因为您不会立即得到反馈。

直接交付通常可以侥幸成功并不意味着它是一种可靠的方法。

要查看 SMTP 对话的哪一部分花费了很长时间，请设置 $mailer->SMTPDebug = 2; 并观察输出（尽管不要在您的实时站点上这样做！）。

Answer 2

不知道 PHPMailer 是否对您是强制性的，但如果不是，我推荐SwiftMailer。

根据我的个人经验，它确实快速可靠。

谢谢。

include_once "inc/swift_required.php";

$subject = 'Hello from Jeet Patel, PHP!'; //this will Subject
$from = array('jeet@mydomain.com' =>'mydomain.com'); //you can use variable

$text = "This is TEXT PART";
$html = "<em>This IS <strong>HTML</strong></em>";

$transport = Swift_SmtpTransport::newInstance('abc.xyz.com', 465, 'ssl');
$transport->setUsername('MYUSERNAME@MYDOMAIN.COM');
$transport->setPassword('*********');
$swift = Swift_Mailer::newInstance($transport);



    $to = array($row['email']  => $row['cname']);
    $message = new Swift_Message($subject);
    $message->setFrom($from);
    $message->setBody($html, 'text/html');
    $message->setTo($to);
    $message->addPart($text, 'text/plain');

    if ($swift->send($message, $failures))
    {
        echo "Send successfulllyy";
    } else {
        print_r($failures);

    }
