Problem with registration email

I created a form which replace the Joomla default one. But when a user registers he receive two email: my custom email and the defualt Joomla confirmation mail. How can I disable the sending of the Joomla default mail?
Thanks

Hi abaddon ,

You should be able to select this in the Plug-in configuration? If you still get both I'm not sure what is happening.

I had to set the template to "NO". in this case the user receive only the custom email. Thanks anyway
