mail function returns true w/bad address

[atdawgie]

I have the following code:
if (mail($mail_to, $mail_subject,$mail_body,$sendmail_from))
echo "<h4>Followup email sent</H4>";
else
echo "<h4>Mail not delivered, check email address</h4>";

No matter if the $mail_to address is bad the function returns true.

Thanks.

Thats because all mail() does is send the mail to your local mail handler. Since your local mail handler accepts the email then as far as PHP is concerned this is a success.
