PHP脚本拒绝发送到Outlook.com

This seems like a reoccurring problem with outlook.com for many individuals.

My script below works with @college.edu, @gmail.com , but on outlook.com - it refuses to reach even the junk folder, nevermind the inbox - how can I modify it to fix it?

I have checked my sender domain to ensure it is not blacklisted.

Script:

<?php
$doraccount = 'noreply@mydomain.com';

$pathwayurl = $_POST['pathway_url'];

$to = $_POST['email_address'];
$subject = "Path Share";
#message for email
$message = '<html><body><div style=width:362px;display:block;margin:0% auto;>';
$message .= "<img src='http://domain.com/sites/default/files/togo3.gif' alt='my site' /></div>";
#$message .= '<table rules="all" style="border-color: #666;" cellpadding="10">';
#$message .= "<tr style='background: #eee;'></tr>";
$message .= '<div><p>Thank you for using Pathway tool. We have provided you with a link to the below.  Please check out our other programs and offerings on the <a href="http://www.oursite.com">our site website</a></p>';
$message .= "<br /><br /><strong>link:</strong> <tr><td>" . $pathwayurl ."</div>";
$message .= '<div><p>The Team<br /><a href="mailto:info@domain.com">info@domain.com</a></p></div>';;
$message .= "</body></html>";

$headers  = "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL;
$headers .= "From: " . $doraccount . PHP_EOL;

if(mail($to,$subject,$message,$headers)){
    echo "<div style=text-align:center;>
            <img src='http://domain.com/sites/default/files/togo3.gif' alt='domain' /> <br />
            <strong>The email was successfully sent.</strong>
            <br> Redirecting you back to the pathway. 
         </div>";
    header('Refresh: 3;url='.$pathwayurl);
    #echo $message;


} else {
    echo "The email was NOT sent.";
}
?>

You redefine your header a few times. You want the following:

$headers  = "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL;
$headers = "From: " . $doraccount . "
" . PHP_EOL;

$headers  = "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL;
$headers .= "From: domain<$from>" . PHP_EOL;

First you set the $header to MIME-Version: 1.0" . PHP_EOL, then add "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL. Then you overwrite all previous data with "MIME-Version: 1.0" . PHP_EOL; $headers .= "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL; $headers .= "From: domain<$from>" . PHP_EOL;. The next line you clear the $header, and set it to "MIME-Version: 1.0" . PHP_EOL, followed by "Content-Type: text/html; charset=ISO-8859-1" . PHP_EOL and "From: domain<$from>" . PHP_EOL. In the end, your header is as following:

MIME-Version: 1.0

Content-Type: text/html; charset=ISO-8859-1

From: domain<$from>

You overwrite your old From header, so this might make Outlook think it's a spam mail and blacklist it immediatly (so it doesn't even reach the spam folder)
