My mails using php mail() are going to the junk mail folder - why?
<?php
ob_start();
session_start();
//define the receiver of the email
$from='mrashidap@gmail.com';
$to = 'mrashidap@gmail.com';
//define the subject of the email
$subject = 'inform me please, when u receive this mail';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with \r\n
#Now We Can Use HTML Tags
$headers = "From: " . strip_tags($from). "\r\n";
$headers .= "Organization: appstribes\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Reply-To: ".($from) . "\r\n";
$headers .= "Return-Path: ".($from) . "\r\n";
$headers .= "X-Priority:3 \r\n";
$headers .= "X-Mailer: PHP". phpversion() ."\r\n";
$headers .= "X-MSMail-Priority: high\r\n";

$msg .= '<p>Dear Sir/Madam</p><br/>';
$msg .= '<p><strong>GOOD DAY..!!!</strong></p>';
$msg .= '<p>Thank you for contacting Keita Customer Service. We regret any inconvenience you have experienced. Your request has been received, and a ticket has been created for you with,</p>';

$message=$msg;
//send the email
$mail_sent = @mail( $to, $subject, $message, $headers );
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed"
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
Most of the mails are going to junk. However mail sending to gmail are getting in inbox itself.
