电子邮件在到达垃圾邮件文件夹前被阻止

$transport = Swift_MailTransport::newInstance();
$messages1 = "
<!DOCTYPE>
<html>
    <body>

          <br>

$messages2 = "Use the URL to verify your account: ".$mail."";
$message = Swift_Message::newInstance();
$message->setContentType("text/plain");
$message->setTo($to);
$message->setSubject("Account Verification");
$message->setBody($messages2);
$message->addPart($messages1);
$message->setFrom(array("contact_us@satperfectscore.com"=> "SAT Perfect Score"));


$mailer = Swift_Mailer::newInstance($transport);
$mailer->send($message);

The message never reaches the recipient .. when I open cPanel's Email Trace I get the following error:

what i'm doing wrong here? I am not even reaching the spam folder..

It's because your server's IP is blocked by the destination mail server. Your server's IP is on their black list so instead of moving your emails to spam folder, they simply ignore your emails.

To make sure you're blocked, try sending an email to a Gmail address.

As the error says, you can go to this link for unblocking your server: http://fp.outboundfiltering.com/?str=0001.0
