ORA-24247: network access denied by access control list (ACL)
ORA-06512: at “SYS.UTL_TCP”, line 19
ORA-06512: at “SYS.UTL_TCP”, line 280

This error message means that no access control list has been assigned to the host you (your application) are trying to access, or no required privileges have been granted to the user by adding user to the ACL.
Solution :
Step 1:
SQL> grant execute on utl_http to scott;
Grant succeeded.
Step 2:  Conn as sysdba
BEGIN
DBMS_NETWORK_ACL_ADMIN.CREATE_ACL (
acl => ‘scottdev.xml’,
description => ‘Permissions to access  mail’,
principal => ‘SCOTT’,
is_grant => TRUE,
privilege => ‘connect’,
start_date => SYSTIMESTAMP,
end_date => NULL);
COMMIT;
END;
/
PL/SQL procedure successfully completed.
Step 3:
SQL> begin
2 DBMS_NETWORK_acl_ADMIN.ADD_PRIVILEGE(
3 acl => ‘scottdev.xml’,
4 principal => ‘SCOTT’,
5 is_grant => true,
6 privilege => ‘resolve’
7 );
8 COMMIT;
9 END;
10 /
PL/SQL procedure successfully completed.
Step 4:
SQL> BEGIN
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL (
acl => ‘scottdev.xml’,
host => ‘*’);
COMMIT;
END;
/

Step 5:
select acl , host , lower_port , upper_port from DBA_NETWORK_ACLS;
select acl , principal , privilege , is_grant from DBA_NETWORK_ACL_PRIVILEGES
Step 6: Send mail as scott user
SQL> begin
send_mail(‘test’,’azarmohds@gmail.com’);
end; 2 3
4 /
PL/SQL procedure successfully completed.

Drop ACL :
BEGIN
DBMS_NETWORK_ACL_ADMIN.drop_acl (
acl => ‘scottdev.xml”);
COMMIT;
END;
/
