DB Feature Usage shows "Real Application Security" used

Hello,

I want to send e-mails from a SE2 database using package UTL_SMTP.

To give access to the network, I used the following commands:

BEGIN

   DBMS_NETWORK_ACL_ADMIN.CREATE_ACL   ('kfsdba.xml', 'Access for UTL_SMTP,UTL_TCP,UTL_HTTP,UTL_MAIL', 'KFSDBA', TRUE, 'connect');

   DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('kfsdba.xml', 'KFSDBA', TRUE, 'connect');

   DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL   ('kfsdba.xml','*');

END;

Now in Database Express of the DB Oracle 12.1.0.2 (Standard-Edition 2) it is shown usage of the feature "Real Applicaion Security" --> "Number of ACLs created: 22

- Is this a license violation?

- How else can I give the package UTL_SMTP access to the network?
