I assume you mean you don't get this >>
What SV is saying is that to help host know where your PHP file is if you are sending out spam (ie: by reading this line, if someone forwards email to host reporting it as spam), they set it to include the following header for example:
X-PHP-Script:
www.yourdomain.com/yourfolder/emailer.php for 209.255.255.255
*** Above is domain...some server admins set it up to show path instead:
/home/username/yourfolder/emailer.php
That would tell them that the script that sent the email was at
www.yourdomain.com/yourfolder/emailer.php and that it was sent using a browser with IP# 209.255.255.255 , for example. That way host knows what script to go investigate. THIS is good on the server-end, as helps catch spammers. The BAD part is that it tells anyone who gets the email what URL they can go to abuse the script themselves - SO, password protect scripts or directories that send email, or make them part of coding whereby just visiting the URL itself with known variables attached doesn't just send-out emails!
