My mail function was disabled, i asked hosting to enable it. Now my mail function is not producing any warning. It is saying that email sent successfully. But Email is not sending.
i tried it even simple mail function. But it is not working.
I would suggest creating a blank .php document with a simple mail sending function on it. If this does not work I would recommend that you contact your hosting provider as it could be another issue with their setup.
Ask the hosting again, I faced this once and my hosting had badly configured sendmail path.
