i m trying to send an email with utl_mail using this procedure:

BEGIN
UTL_MAIL.send(sender     => 'o.adahanifi@teletic.dz',
                recipients => 'ao_ada_hanifi@esi.dz',
                subject    => 'UTL_MAIL Test',
                message    => 'If you get this message it worked!');
END;

but i have this error :

ORA-29279: erreur permanente SMTP : 550 authentication.

and before that i used utl_smtp to send emails and worked perfectly since it gives the option of authentication of sender.

so the question is there way to authenticate sender using utl_mail or just stay with utl_smtp.
