PHPMailer：在本地主机上工作，单击域上的 "submit" 按钮后卡住，出现错误 503，电子邮件在 4 分钟后到达

Question

所以我已经尝试了两天来摆脱这个问题。如前所述，该代码在我的 xampp apache 本地主机上运行良好。电子邮件立即发送。但是，在我拥有的域上，一旦我按下提交，它就会加载和加载，并且在 5 分钟左右后超时，或者更确切地说是“503 服务不可用”。我检查了我的本地 PHP 错误日志，一切正常。不过我无法访问服务器上的错误日志。

表单代码如下：

<div class="form-group">
    <label>Ihr Name</label>
    <input type="text" name="name" placeholder="Vorname Nachname" class="form-control"  />
</div>
<div class="form-group">
    <label>Ihre E-Mail Address</label>
    <input type="email" name="email" class="form-control" placeholder="IhreEmail@server.com"  />
</div>
<div class="col-md-6">

    <div class="form-group">
        <label>Ihre Nummer</label>
        <input type="text" name="mobile" placeholder="Ihre Mobile 079 *** ** **" class="form-control" required/>
    </div>
    <hr/>
    <div class="form-group">
        <label><i class="far fa-file"></i>Ihr Dokument für die Übersetzung</label>
        <input type="file" name="resume" accept=".doc,.docx,.pdf,.jpg,.bmp"/>
    </div>
</div>
<div class="form-group">
    <label>Ihre Nachricht</label>
    <textarea name="additional_information" placeholder="Welchen Service wünschen Sie? Wie sollen wir in Kontakt treten?" class="form-control" required rows="8"></textarea>
</div>
<div class="form-group" align="center">
    <input type="submit" name="submit" value="Senden" class="btn btn-lg btn-success"/>
</div>
</form>

有个include_once('mail.php');在 index.php 当然，表格所在的位置。 mail.php 看起来像这样：

<?php


use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

// HIDE ALL ERRORS
//error_reporting(0);
//ini_set('display_errors', 0);


$message = '';


if ( isset( $_POST['submit'] ) ) {


    if ( isset( $_FILES['resume']['name'] ) && $_FILES['resume']['name'] != "" ) {

        $path = 'upload/' . $_FILES['resume']['name'];
        //print_r($path);
        print_r( $_FILES );

        move_uploaded_file( $_FILES["resume"]["tmp_name"], $path );
    } else
        $_FILES = NULL;
    $message = '
    <h3 align="center">Applicant Details</h3>
    <table border="1" width="100%" cellpadding="5" cellspacing="5">
        <tr>
            <td width="30%">Name</td>
            <td width="70%">' . $_POST["name"] . '</td>
        </tr>
    
        <tr>
            <td width="30%">Email Address</td>
            <td width="70%">' . $_POST["email"] . '</td>
        </tr>
        <tr>
            <td width="30%">Phone Number</td>
            <td width="70%">' . $_POST["mobile"] . '</td>
        </tr>

        <tr>
            <td width="30%">Additional Information</td>
            <td width="70%">' . $_POST["additional_information"] . '</td>
        </tr>
    </table>
';
    require 'vendor/phpmailer/phpmailer/src/PHPMailer.php';
    require 'vendor/phpmailer/phpmailer/src/SMTP.php';
    require 'vendor/phpmailer/phpmailer/src/Exception.php';
    require 'vendor/autoload.php';

    $mail = new PHPMailer( true );
    $mail->IsSMTP(); //Sets Mailer to send message using SMTP

    // ADD YOUR DETAILS HERE
    //$mail->Host = 'smtp.gmail.com'; //Sets the SMTP hosts of your Email hosting
    $mail->Host = 'smtp.iway.ch '; //Sets the SMTP hosts of your Email hosting, this for Godaddy
    $mail->Port = '587'; //Sets the default SMTP server port
    $mail->SMTPAuth = true; //Sets SMTP authentication. 
    $mail->Username = 'email@email.com'; //Sets SMTP username
    $mail->Password = 'example'; //Sets SMTP password
    $mail->SMTPSecure = 'tls'; //Sets connection prefix. Options are "", "ssl" or "tls"

    $mail->setFrom( 'email@email.com', 'example' ); //Sets the From email address for the message
    $mail->addAddress( 'example@server.com' );
    $mail->SMTPDebug = 0;
    $mail->WordWrap = 50;
    $mail->IsHTML( true ); //Sets message type to HTML
    if ( isset( $_FILES['resume']['name'] ) && $_FILES['resume']['name'] != "" ) {
        $mail->AddAttachment( $path ); //Adds an attachment from a path on the filesystem
    }
    $mail->Subject = 'Emaple Mail'; //Sets the Subject of the message
    $mail->Body = $message; //An HTML or plain text message body

    try {
        $mail->send();
        header( "Refresh:3; url=index.php" );
        exit();
    } catch (phpmailerException $e) {
        echo $e->errorMessage();
        echo $e->getMessage();
    }

}

电子邮件名称和密码是故意更改的。我真的束手无策。这是我的第一个 Hompeage，其他一切都很好。为什么它在 5 分钟后发送电子邮件，但显示 503 而不是 index.php？谢谢。

Answer 1

我认为您应该将 SMTP port 和 SMTP Secure 更改为：

$mail->Port = '465';
$mail->SMTPSecure = 'ssl';

PHPMailer：在本地主机上工作，单击域上的 "submit" 按钮后卡住，出现错误 503，电子邮件在 4 分钟后到达

PHPMailer: Working on localhost, stuck after clicking "submit" button on the domain, gives Error 503, E-Mail arrives after 4mins
