WampServer: 警告: mail(）: SMTP 服务器响应: 530 5.7.0 必须先发出 STARTTLS

我在使用WampServer时遇到问题，我尝试创建联系表单，但它不起作用。BIOS 停止识别我的 2GB RAM 芯片，所以我的系统认为它是 32 位而不是 64 位。下面是 PHP 错误表：

( ! ) Warning: mail(): SMTP server response: 530 5.7.0 Must issue a STARTTLS command first. 8sm9902426ioe.8 - gsmtp in C:'Users'miner'Desktop'Configuration Creator'www'contact'mail.php on line 10
Call Stack
#   Time    Memory  Function    Location

2   0.0004  246648  mail ( )    ..'mail.php:10

这是我的代码：

联系方式.html

<form action="mail.php" method="POST">
    <input type="text" class="form-control" name="name" placeholder="Name">
    <div class="padded-bottom"></div>
    <input type="text" class="form-control" name="email" placeholder="Email">
    <div class="padded-bottom"></div>
    <input type="text" class="form-control" name="subject" placeholder="Subject">
    <div class="padded-bottom"></div>
    <textarea type="text" class="form-control no-resize paragraph" rows="8" name="message" placeholder="Message"></textarea>
    <div class="padded-bottom"></div>
    <button type="submit" class="btn btn-default">Submit</button> <button type="reset" class="btn btn-default">Clear Form</button>
</form>

邮件.php

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$from = 'From: '. $name; 
$to = 'email@example.com'; 
$subject = $subject;
$body = "From: $name'n Email: $email'n Message:'n $message";     
if (mail ($to, $subject, $body, $from)) { 
    echo '<p>Your message has been sent!</p>';
} else { 
    echo '<p>Something went wrong. Please manually <a href="mailto:email@example.com">email me</a> and include a screenshot/copy of the log above.</p>'; 
}
?>

最后，PHP.ini

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = smtp.gmail.com
; http://php.net/smtp-port
smtp_port = 587
; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = email@example.com

对不起，如果是重复的，我的问题与其他问题不同。
