Requesting index.php via AJAX does run the whole script, but in order to have the mail function work properly, your AJAX request must supply the script with the proper resources as if it were to be ran directly.

A PHP script called via AJAX should still be able to send an email.

What parameters are you using through index.php to generate the mail? Are they GET or POST variables? Does the AJAX call include those variables?

Have you run basic debugging in the index.php file? Just using file_put_contents( 'debug.txt' , 'Debug Data' , FILE_APPEND )?
