# Error When Redefining Pluggable Function

 * I am trying to create a plugin to modify the wp_mail function in the pluggable.
   php file. I understand that to do this I simply need to define it somewhere else
   and WordPress will handle the rest.
 * If that’s the case, why do I get this error when I activate my plugin?
 * `Fatal error: Cannot redeclare wp_mail() (previously declared in .../wp-includes/
   pluggable.php:271)`

 * So nobody has any idea why this is happening?
