I am trying to send mail() to a Google APPS domain I have setup. The code is simple:

PHP Code:
('jake@benjaminsrealty.com''Subject Line''Message body.'null'-fydev_steve@hotmail.com');
And yet for some reason the email is not sent through! It sends it to Hotmail, Gmail and every other accnt I have tried. Is this a server issue? Or does Google APPS have criteria for mail() functions that I am missing?
