[BlueOnyx:27293] Error sending mail with PHP script.

[Colin Jack]

Good afternoon.

My brain doesn't seem to be working today so if someone can help it would be appreciated!

We have migrated a customer vsite from 5209R to 5210R using easymigrate and all good.
5210R is up to date.

The site uses php to send mail from their website and this has always worked fine - until now.

Simple script:

// Define the recipient's email address
$to = "carl at domain.co.uk";

// Define the subject of the email
$subject = "Test Email from PHP";

// Define the message body
$message = "Hello, this is a test email sent from a PHP script.";

// Define additional headers
$headers = "From: intranet at domain.co.uk"."\r\n";
$headers .= "Reply-To: intranet at domain.co.uk"."\r\n";
$headers .= "X-Mailer: PHP/".phpversion();

// Send the email
if(mail($to,$subject,$message,$headers)){
    echo "Email sent successfully.";
}else{
    echo "Failed to send email.";
}

The script returns "Email sent successfully." ... but it wasn't!

Email is disabled on the vsite
I can use dig on the server to get correct MX 

I would appreciate any ideas that I have not considered. __

Thanks
