How to change the "from" header while sending an email from cpanel? - php

Question

I'm trying to send email to my gmail account from my website using mail() function. This is working fine but the problem is, when I receive the mail in my gmail account inbox ( not in spam ), there is a '?' mark instead of a regular blank profile picture. When I hover over the '?' mark, a message pops up saying,"Gmail couldn't verify that mywebsite.com actually sent this message (and not a spammer)". I have added two pictures of this issue. I contacted to my hosting provider and they told me that it was a script related issue. They analyzed the file which I got by clicking on "Show original" in my gmail inbox. They said that, the problem occurred because the 'from' email address that gmail got was "cpanel-username#server-hostname.com" instead of "myemail#website.com". I have to replace "cpanel-username#server-hostname.com" with "myemail#website.com". I tried a lot but was unable to change the "from" header. My code is something like this
$Email = "myemail#gmail.com";
$message = "Hello!!";
$headers = "From: Mywebsite <noreply#mywebsite.com>";
$sentmail = mail("$Email",'Something Important',"$message",$headers);
Note that, "noreply#mywebsite.com" is a real email address which I created in my cpanel. I also tried phpmailer to solve this issue but I did not succeed. My phpmailer code is like this
require 'mailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isMail(); // I also tried $mail->isSMTP(), but it does not work. Just keeps loading the page but never completes.
$mail->Host = 'localhost';
$mail->SMTPAuth = true;
$mail->Username = 'noreply#mywebsite.com';
$mail->Password = '****************';
$mail->SMTPSecure = 'tls';
$mail->Port = 365;
$mail->setFrom('noreply#mywebsite.com', 'Mywebsite');
$mail->addAddress('myemail#gmail.com');
$mail->isHTML(true);
$mail->Subject = 'Something Important';
$mail->Body = 'Hello!!';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
But this also does not solve my problem. The from header is still "cpanel-username#server-hostname.com" when the mail is received in gmail. Please someone help me with this issue.

you can add the -f user#domain.tld to a mail.force_extra_parameters line in your php.ini.
