SMTP server problem for UTL_MAIL ..

Question

Hi ,
I asked the Mail server admin and he said that the relaying is set to allow on the settings , the procedure still cant send to outside domains :
SQL> alter system set SMTP_OUT_SERVER ='oursmtp';
SQL>CREATE OR REPLACE PROCEDURE send_email
AS
   BEGIN 
     UTL_MAIL.SEND(sender => '[email protected]',
                   recipients => '[email protected]',
                   cc => null,
                   bcc => null,
                   subject => 'Msg From Oracle DB',
                   message => 'test msg');
   EXCEPTION
   WHEN OTHERS THEN
     raise_application_error(-20001,'The following error has occured: ' || sqlerrm);  
END;
SQL>exec  send_email ;
BEGIN send_email ; END;
ERROR at line 1:
ORA-20001: The following error has occured: ORA-29279: SMTP permanent error: 550 5.7.1 Unable to relay for [email protected]
ORA-06512: at "SCOTT.SEND_EMAIL", line 15

Try my method of sending mail using UTL_SMTP package. Of course, it's not my own method (which I created:)), but I use it to send mail with attachment :)
