mail() max loop

[westman]

I have used this code...

$to = '1@gmail.com';
$to2 = '2@gmail.com';
$to3 = '3@gmail.com';

mail($to, $subject, $message, $headers);
mail($to2, $subject, $message, $headers);
mail($to3, $subject, $message, $headers);

And it works well to send mail to many people at the same time.
I have sent mail to 20 people at the same time with this code.
My question is:
Is there a maximum number (a limit) of emails this code method will work with?
