How to disable registration email in joomla

I found the answer to this if anyone is still looking.

edit YourSite/administrator/components/com_users/controller.php

***NOTE*** make sure you're in ADMINISTRATOR/components directory and not the general components directory off of the root... or you will [drive] yourself crazy looking for something that doesn't exist like I did

around line 189 look for "JUtility::sendMail( $adminEmail, $adminName, $user->get('email'), $subject, $message );"
and comment out or delete that 1 line.

So far so good... I have registered a handful of test users and received no registration confirmation email & mass mailing still works.

 

...........OR.........

 

I found if you want to disable the annoying email when a front end user joins your site, I had to alter:
components\com_user\controller.php
Line 522
comment out:
//JUtility::sendMail($mailfrom, $fromname, $row->email, $subject2, $message2);

--------OR--------------

Hello, you need to modify the file /components/com_user/controller.php wich is not in the administrator folder... delete these code... and thats it..

// Send email to user
if ( ! $mailfrom || ! $fromname ) {
$fromname = $rows[0]->name;
$mailfrom = $rows[0]->email;
}

JUtility::sendMail($mailfrom, $fromname, $email, $subject, $message);

The administrator continue receiving mails but the registered user wont.
If you want neither the admin receive mail delete the code after the // Send notification to all administrators

It works fine for me.
