Description:
------------
Hi, I ran accross something while writing an e-mail contact form for a customer. I have hosting provider still on PHP 4.3.2. I am changing providers soon though. But anyways, what I noticed is the mail() function only allows 5 arguments. 

So, what I wanted to ask/propose, is to see if perhaps I can suggest/request there be 7 - 10 arguments allowable in the mail() function. Five seems a bit limited, and I think a max of 10 would be reasonable. Beyond 10 would probably be a little rediculous, but 10 should suffice. 

I don't see this as necessarily a "bug" per say, but a feature that would make it a lot easier. 

Here is an example of the problem at hand.

Reproduce code:
---------------
//HTML Form Code - ContactUs.html
<form name="email" method="post" action="mail.php">
Name <input type="text" name="name" id="name" />
Address <input type="text" name="addr" id="addr" />
E-Mail <input type="text" name="from" id="from" />
Message <textarea rows="10" cols="20" name="notes" id="notes"></textarea>
<input type="submit" value="SEND" />
</form>

//PHP Code - mail.php
<?php
$date = date(r);
$to = "support@example.com";
$from = $_POST['from'];
$subject = "Example.com Support Inquiry - From Website";
$message = $_POST['notes'];
$address = $_POST['addr'];
if(mail($to, $date, $from, $subject, $message, $address)) {
echo "Message Sent";
} else {
echo "Message Failed";
}
?>

Expected result:
----------------
Page should say:

Message Sent

Actual result:
--------------
Warning: mail() expects at most 5 parameters, 6 given in /var/www/html/mail.php on line 8
Message Failed
