php5 Mail Header Patch

[Olivier Mueller]

Hello Alex,

Would it be possible for you to add this patch to the php port as
an option? :  http://choon.net/php-mail-header.php

It adds such headers to all mails sent via the php mail() function:
X-PHP-Script: www.example.com/~user/testapp/send-mail.php for 10.0.0.1
Very practical to track php-based spamming.

Regards,
Olivier
