How to override wordpress wp_mail function

HI,

I have a problem in overriding the wp_mail function, Actually I want to send an extra email every time a wp_mail function called.

There are many places in WordPress where the wp_mail function is in use, and there may be some new plugin installed which may use the wp_mail,

so my requirements are to send an extra email when wp_mail function called.

I am trying it in this way but unable to find a way to get the parameters which I have to pass to my new mail function.

add_filter(‘wp_mail’,’my_mail_func’);
function my_mail_func(){
@mail($to,$from,$message,$headers);
}

How can get the parameters?

Please help

Thank you.
