ACL for Sending e-Mail with APEX Oracle 11.2 - oracle

Question

I'm trying to send e-Mail as a simple Send e-Mail process with Oracle APEX 11.2, and I can't figure out how the correct ACL has to be set. I tried this, but no success, still getting: ORA-24247: network access denied by access control list (ACL). What am I doing wrong?
SELECT * FROM dba_network_acl_privileges shows that all rules are granted and also select * from dba_network_acls shows both rules.
Thanks in Advance!
BEGIN
DBMS_NETWORK_ACL_ADMIN.DROP_ACL (acl => 'send_mail.xml' );
DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('send_mail.xml','Allow mail to be send', 'APEX_050100', TRUE, 'connect');
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('send_mail.xml','APEX_050100',TRUE, 'connect');
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('send_mail.xml','APEX_050100',TRUE, 'resolve');
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL (acl => 'send_mail.xml',host => '*',lower_port => null, upper_port => null);
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL (acl => 'send_mail.xml',host => 'smtp.google.com',lower_port => null, upper_port => null);

This is how I do it.
-- Drop ACL ====================================================================
BEGIN
DBMS_NETWORK_ACL_ADMIN.drop_acl (acl => 'mydba.xml');
END;
/
-- Create ACL ==================================================================
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'mydba.xml',
description => 'SMTP, MAIL, HTTP Access',
principal => 'LITTLEFOOT',
is_grant => TRUE,
privilege => 'connect',
start_date => NULL,
end_date => NULL);
END;
/
-- Assign ACL ==================================================================
BEGIN
DBMS_NETWORK_ACL_ADMIN.assign_acl (acl => 'mydba.xml',
HOST => '*',
lower_port => NULL,
upper_port => NULL);
END;
/
-- Add privilege ===============================================================
BEGIN
-- LITTLEFOOT
DBMS_NETWORK_ACL_ADMIN.add_privilege (acl => 'mydba.xml',
principal => 'LITTLEFOOT',
is_grant => TRUE,
privilege => 'connect',
start_date => NULL,
end_date => NULL);
DBMS_NETWORK_ACL_ADMIN.add_privilege (acl => 'mydba.xml',
principal => 'LITTLEFOOT',
is_grant => TRUE,
privilege => 'resolve',
start_date => NULL,
end_date => NULL);
END;
/
COMMIT;
When new users require privileges, I just copy/paste LITTLEFOOT's data from the "Add privilege" procedure and change principal's name (currently, there are dozen of users in my script).
