    `Fatal error: Uncaught exception'
   phpmailerException' with message 'Invalid address: ' in ....wp-includes/class-
   phpmailer.php:797 Stack trace: #0 ....wp-content/plugins/easy-wp-smtp/easy-wp-

 * Hi,
 * It seems it complained about an invalid email address when NinjaFirewall’s sent
   you an email at the end of the installation process.
    I think you should click
   on “NinjaFirewall > Event Notifications” and check the contact email address 
   to ensure it is correct, otherwise you may not receive alerts and notifications.
   You can also test if notifications work simply by logging out of the admin dashboard
   and then logging in again. You should receive an email alert from the firewall.

 * Can you try to disable the Easy WP SMTP plugin, install NinjaFirewall and then
   re-enable Easy WP SMTP right after the installation ?
