PHP Mail，其中某些电子邮件未收到该电子邮件

Question

I have my clients server – let's call it clientserver.com .

Emails sent from the server using the PHP mail function don't get received by an email account on that server – let's call it email@clientserver.com . However, if I set the email ID to my own personal one it is received without any problem.

Is there anything you guys can see that I could possibly add to the headers or anything else to ensure that this email@clientserver.com address receives the contact form email?

I've tried PHPMailer with no luck either.

<?php

if(empty($_POST['name']) || empty($_POST['email']) || empty($_POST['message'])) {
    die('Error: Missing variables');
}

$name=$_POST['name'];
$email=$_POST['email'];
$phone=$_POST['phone'];
$message=$_POST['message'];

$to='email@clientserver.com';

$headers = 'From: '.$email."\r\n" .
    'Reply-To: '.$email."\r\n" .
    'MIME-Version: 1.0' . "\r\n" .
    'Content-type: text/plain; charset=iso-8859-1' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();
$subject = 'Contact form enquiry';
$body='Dear Client,'."\n\n";
$body.='The following enquiry has been sent through.'."\n\n";
$body.='Name: '.$name."\n";
$body.='Email: '.$email."\n";
$body.='Phone: '.$phone."\n";
$body.='Message: '.$message."\n";

if(mail($to, $subject, $body, $headers, "-femail@clientserver.com")) {
    die('Mail sent');
} else {
    die('Error: Mail failed');
}

?>

Sometimes you have to define security settings among other things, some smtp servers accept different details. I had a problem similar to this and i also had to allow the php extension "php_opnessl".

for example: live uses a setup like this

$mail -> Port = 587;
$mail -> SMTPSecure = "tls"; 
$mail -> Host = "smtp.live.com";

while gmail is:

$mail -> Port = 465;
$mail -> SMTPSecure = "ssl"; 
$mail -> Host = "smtp.gmail.com";

Let me know if any of this helps
