Solution:

From 11g onward, to send mail using UTL_MAIL or UTL_SMTP , ACL need to be created in the database.

SQL> alter system set smtp_out_server='mail.abuzer.local' scope=both;
 
System altered.

--- creating ACL as below 
exec DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('send_mail.xml','Allow mail to be send', 'USR_ABUZER', TRUE, 'connect');
commit;
----Grant the connect and resource privilege as below
exec DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('send_mail.xml','USR_ABUZER',TRUE, 'connect');
exec DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE('send_mail.xml','USR_ABUZER',TRUE, 'resolve');
exec DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('send_mail.xml','*',587);
commit;
 

conn usr_abuzer/password
Connected.
SQL> begin
  utl_mail.send(sender     => 'admin@abuzer.local',
                recipients => 'admin@abuzer.local',
