Hello
I have a website and I have email named "[email protected]".
I'm trying to send emails from it by PHP page.

I was using this code:
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=windows-1256\r\n";
$headers .= "From: My Name <[email protected]>\r\n";
$to = The email which I wanna send to... (Hotmail email).
$message = "<html><body><p align=center>Hello</p></body></html>";
mail ($to,"Subject",$message,$headers);

Since days, it was working but now it can't send emails.
Emails never come to receivers.

What's problem, please?
I need help.

Thanks & Regards
