Setting E-mail Preferences
Both the $from_ and $to_ e-mail addresses within the configuration files are for the administration only.

$from_email = "email@domain.com"; $to_email = "email@domain.com";

Make sure you fill in all the information for your smtp mail server.

The first e-mail is the address that "sends" the administrator e-mail notification when a Licence key is automatically disabled.

The second e-mail is the administration e-mail address to receive the automated notifications.

You can use either a single e-mail address or two different addresses but make sure all other configurations are setup correctly.
