php联系表格 - 发送给垃圾邮件的电子邮件

Question

我有一个自定义的html联系表格添加到我的一个与php表单（send-mail.php）集成的网站。邮件会通过POST方法发送到指定地址，您可以在下面粘贴的代码中看到。

已收到的电子邮件已发送到收件人收件箱中的垃圾邮件文件夹，因此一段时间未被发现。收件人电子邮件客户端是AOL。

是否有任何修改，我可以对我的代码，以确保所有电子邮件到达收件箱？

我对HTML/PHP代码形式都低于...

感谢

<form action="send-mail.php" method="POST"> 
    <div class="form-group">  
     <label for="field_name" class="col-md-3 control-label">Name:</label> 
     <div class="col-sm-8">  
      <input type="text" class="form-control" id="field_name" name="sender_name">  
     </div> 
    </div> 

    <div class="form-group"> 
     <label for="field_email" class="col-md-3 control-label">Your e-mail:</label> 
     <div class="col-sm-8">  
      <input type="text" class="form-control" id="field_email" name="sender_email"> 
     </div> 
    </div> 

    <div class="form-group"> 
     <label for="field_phone" class="col-md-3 control-label">Subject:</label> 
     <div class="col-sm-8">  
      <input type="text" class="form-control" id="field_phone" name="sender_phone"> 
     </div> 
    </div> 

    <div class="form-group"> 
     <label for="field_message" class="col-md-3 control-label">Message:</label> 
     <div class="col-sm-8">  
      <textarea id="field_message" class="form-control" rows="14" name="sender_message"></textarea> 
     </div> 
    </div> 

    <div class="form-group"> 
     <div class="col-sm-10 col-sm-offset-3"> 
      <input type="submit" class="btn btn-info" name="send_message" value="Send"> 
     </div> 
    </div> 
</form> 

PHP形式...

<?php  
$mail_to  = '[email protected]'; 

$name   = $_POST['sender_name'];  
$mail_from  = $_POST['sender_email'];  
$phone   = $_POST['sender_phone'];  
$message  = $_POST['sender_message'];  

$subject  = 'Mediation East Sussex - Message from ' . $name;  

$body_message = 'From: ' . $name . "\r\n";  
$body_message .= 'E-mail: ' . $mail_from . "\r\n";  
$body_message .= 'Phone: ' . $phone . "\r\n";  
$body_message .= 'Message: ' . $message; 

$headers  = 'From: ' . $mail_from . "\r\n";  
$headers  .= 'Reply-To: ' . $mail_from . "\r\n";  

$mail_sent  = mail($mail_to, $subject, $body_message, $headers);  

if ($mail_sent == true){ ?> <script language="javascript" type="text/javascript">   
    alert('Thank you for the message. We will contact you shortly.');   
    window.location = 'contact_us.html';   
    </script> 
<?php } else { ?>  
    <script language="javascript" type="text/javascript">   
    alert('Message not sent. Please, notify the site administrator [email protected]');   
    window.location = 'contact-form.html';  
    </script>  
<?php  
} 
?>

垃圾邮件不是100％的代码依赖。 20％取决于代码，80％取决于SMTP服务器信誉（您可以从https://www.senderscore.org/获得此分数）。

所以不是代码和垃圾邮件之间的直接关系。

然而，你可以提高你的电子邮件的以下一些通用规则 http://www.inc.com/geoffrey-james/how-to-avoid-a-spam-filter-5-rules.html http://mailchimp.com/resources/guides/how-to-avoid-spam-filters/html/

在我的经验中的内容，您可以添加所有这些规则，也是你的电子邮件可以到达垃圾邮件的收件箱。

我希望它适合你。
