A possible solution to remove this would be to use Phpmailer to upload.

First download via Poser in your project folder (your use Composer):

composer require phpmailer/phpmailer

Or download the latest Release on: https://github.com/PHPMailer/PHPMailer/releases

If you downloaded the folder PHPMailer-5.2.14 in the folder that is your script, the folder structure should be something like:

./projeto
    |---- enviaremail.php
    |---- PHPMailer-5.2.14/
            |---- PHPMailerAutoload.php
            |---- ...

email.php:

<?php
require 'PHPMailer-5.2.14/PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                               // Pra depurar o código remova o // do começo

$mail->isSMTP();                                      // Define como SMTP
$mail->Host = 'smtp.exemplo.com';                     // Endereço do SMTP
$mail->Port = 25;                                     // Porta do SMTP
$mail->SMTPAuth = true;                               // Autenticação no SMTP
$mail->Username = '[email protected]';              // SMTP username
$mail->Password = 'senha';                            // SMTP password

//$mail->setFrom('[email protected]', 'Mailer');       //comentei esta linha pois o Gmail irá detectar se tentar alterar o "from", mas pode tentar

//Adiciona destinatários:

$mail->addAddress('[email protected]', 'Joe User');     // Adiciona destinatário
$mail->addAddress('[email protected]');               // Destinatário sem nome

$mail->addReplyTo('[email protected]', 'Information');

//Manda como cópia
$mail->addCC('[email protected]');

//Manda como cópia oculta
$mail->addBCC('[email protected]');

//Anexos se precisar    
$mail->addAttachment('/var/tmp/file.tar.gz');
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');


//Habilita HTML
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Assunto';
$mail->Body    = 'Mensagem <b>teste</b>';
$mail->AltBody = 'Mensagem em texto, alternativa ao HTML';

if(!$mail->send()) {
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Mensagem enviada';
}

If to use Gmail as "sender" you will have to unlock in Gmail settings, the settings to use your Gmail account to send emails is:

//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';

// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// Se a rede não suportar SMTP sobre IPv6

$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "[email protected]";
$mail->Password = "yourpassword";

Answer 2

According to own PHP documentation, you can use additional parameters for the Mailer of the system.

If the system is based on sendmail, there is a parameter that can help, the -f:

<?php 
    mail($to, $subject, $message, $headers, "[email protected]"); 
?>

This causes the sendmail identify with the given name when making the SMTP connection.

By default, the sendmail uses the OS configuration, and this is what generates the divergence of addresses, and consequently causes Google to show the two addresses, the "from", which is used by PHP, and the "via", which is removed from the protocol negotiation. The -f does the override of this behaviour.

Important: not always the sendmail allows this override. Some extra configuration may be required directly on the system.

Include the desired information in the header, example:

$headers  = "MIME-Version: 1.1".PHP_EOL;
$headers .= "Content-type: text/plain; charset=iso-8859-1".PHP_EOL;
$headers .= "From: Meu Nome <[email protected]>".PHP_EOL; // remetente no LINUX
$headers .= "Return-Path: [email protected]".PHP_EOL; // return-path
$envio = mail("[email protected]", "Assunto", "Texto", $headers);
