我无法让 xampp 或远程服务器使用我的 php 邮件功能发送电子邮件

我已经在我的计算机上为学校项目安装了 xampp，我还可以访问学校的 apache 服务器，在那里我可以上传我的文件并运行它们。

<?php
$headers.= 'MIME-Version: 1.0' . "'r'n";
$headers.= 'Content-type: text/html; charset=iso-8859-1' . "'r'n";
$rating=$_POST['Rating'];
$subject= "review from website";
$name=$_POST['lname'].", ".$_POST['name'];
$from = $_POST['email'];
$to ="bricebathel@hotmail.com; bbathel@pembaserv.com;".$from.";";
$messageTo="BBComputers";
$headers = "From:" . $from;
$message = htmlspecialchars($_POST['comment']);
$about = $_POST['product'];
$date=date("j-n-y 'a''t g:ia'n");
mail($to,$subject,$message,$headers);
echo "<p id='contactUsData'>Message Sent to: ".$messageTo."<br>Date: ".$date."<br>                       From: ".$name."<br> About: ".$about."<br> Rating: ".$rating."<br> Message:".$message."<//p>";

$file_message="From: ".$name."'nEmail: ".$from."'nAbout: ".$subject."'nRating:   ".$rating."'nMessage: ".$message;
$file= fopen("data/feedback.txt","a")
    or die("Error: Could not open the log file.");
fwrite($file,"'n----------------------------'n")
    or die("Error: Could not open the log file.");
fwrite($file,"Received: ".$date."'n")
    or die("Error: Could not open the log file.");
fwrite($file,$file_message)
    or die("Error: Could not open the log file.");
?>
