php联系表格，是否可以检查是否收到了自动电子邮件？

Question

我一直在四处寻找有关如何确保在 Web 表单中输入的电子邮件地址有效或无效的建议。似乎最好的解决方案是向用户提交的电子邮件地址发送一封自动电子邮件，如果他们收到它，那么如果不是它显然无效，那就太好了。

我想做的是让用户填写联系表格，当他们提交表格时，它会检查所有验证，然后向用户的电子邮件地址发送一封自动电子邮件，然后根据是否成功收到电子邮件发送原始查询到我的电子邮件。

我可以让自动电子邮件发送正常，但有没有办法让 php 返回收到的电子邮件确认，以便我可以处理我的脚本的其余部分？

这是我的代码

<?php
// if user has submitted the form and there are no errors

if(($_SERVER["REQUEST_METHOD"] == "POST") && !$nameErr && !$emailErr && !$phoneErr && !$messageErr && !$botErr && !$pointsErr)
{
    //Create a new PHPMailer instance
    $mail = new PHPMailer;
    //Tell PHPMailer to use SMTP
    $mail->isSMTP();
    //Enable SMTP debugging
    // 0 = off (for production use)
    // 1 = client messages
    // 2 = client and server messages
    $mail->SMTPDebug = 0;
    //Set the hostname of the mail server
    $mail->Host = 'mailout.one.com';
    //Set the SMTP port number - likely to be 25, 465 or 587
    $mail->Port = 587;
    //Whether to use SMTP authentication
    $mail->SMTPAuth = true;
    //Username to use for SMTP authentication
    $mail->Username = 'USERNAME';
    //Password to use for SMTP authentication
    $mail->Password = 'PASSWORD';
    //Set who the message is to be sent from
    $mail->setFrom($from, $name);
    //Set an alternative reply-to address
    $mail->addReplyTo($email, $name);
    //Set who the message is to be sent to
    $mail->addAddress($from, 'PERSON');


    // To send automated reply mail
    $autoemail = new PHPMailer(); 
    $autoemail->From = $from; 
    $autoemail->FromName = "PERSON"; 
    $autoemail->AddAddress($email, $name); 
    $autoemail->Subject = "Autorepsonse: We received your submission"; 
    $autoemail->Body = "We received your submission. We will contact you soon ...";
    $autoemail->Send();



    if(!$autoemail->send()) 
    {
        echo "Mailer Error: " . $mail->ErrorInfo;
    } 
    else 
    {
        //CHECK AUTOMATED EMAIL HAS BEEN RECEIVED BY THE USER THEN SEND THEIR ENQUIRY EMAIL
        //Set the subject line
    #$mail->Subject = $subject;
    //Read an HTML message body from an external file, convert referenced images to embedded,
    //convert HTML into a basic plain-text alternative body
    #$mail->Body = $message."<p><strong>Club Enquiry Relates To: </strong>".$club."</p><p><strong>Client Details</strong></p>Name: ".$name."<br/>Email: ".$email."<br />Tel No: ".$phone."<p><strong>Extras</strong></p>How Did you find our website? ".$hearsay."<br/ >Spam Score: ".$points." out of ".$maxPoints."<br />IP Address: ".$_SERVER['REMOTE_ADDR'];
    //Replace the plain text body with one created manually
    #$mail->AltBody = 'This is a plain-text message body';
    //Attach an image file
    #$mail->addAttachment('images/phpmailer_mini.png');

        echo"<h2>Thank You!!!</h2>";
        echo "<p>Your message has been sent successfully, we aim to respond within a couple of days. Please check your Junk/Span folder incase it ends up there.</p>";
    }   

但我不确定如何判断自动回复电子邮件是否已送达？

非常感谢任何帮助

自动和即时的交付确认是不可能的，因此如果您正在考虑等待该确认让您的脚本执行注册过程的第二部分，您需要重新考虑您的策略。

另外，请记住，有效的电子邮件并不一定意味着该电子邮件属于注册人。理论上，我可以使用我认识的人的电子邮件注册您的网站，并且因为电子邮件存在而可以。

如果您需要电子邮件验证，您应该考虑发送带有唯一一次性链接的自动电子邮件，用户单击该链接以完成该过程，或者包含用户必须在确认步骤中输入的唯一代码。

我的建议是在电子邮件中包含指向您网站的链接（即 yoursite.com/verification/random_unique_string）

random_unique_string 可以是任何东西，只要它不会被恶意用户撤消。例如，它可能是收件人电子邮件、发送日期、随机盐等的哈希值，它是唯一的，当点击时，会导致注册过程的最终确定
