As stated by Erick, Your SPF Is stated as Passed so i would but it down to header malformation in your php main function
This is the code you have:
<?php
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: UzmanKirala <bilgi@uzmankirala.com>\r\n";
$mail_body = "This<br />is<br />a<br />test<br />mail.";
mail('uzmankirala@hotmail.com', 'Subject', $mail_body, $headers);
?>
Google will read this and see that the mail is malformed as there's no boundaries. Lack of correct new lines etc.
I'm not going to bother explaining the whole RFC For the Email Formats but instead point you to a file which I use all the time and works very very well.

Read the class file and unserstand how to use it fully but for now heres a starter example:
$mail = new Mail();
$mail->setTo("mektup@gmail.com");
$mail->setFrom("bilgi@uzmankirala.com");
$mail->setSender("Bilgi");
$mail->setSubject("Test mail");
$mail->setHtml("<b>Some html email</b>");
$mail->send();
