Send email whith oracle

Hi all,
I write from Italy and with this procedure I want send a E-mail from
Oracle.
Ok, all works fine except the messagge body.

-------
CREATE OR REPLACE PROCEDURE send_mail_alen(
v_sender in varchar2,
v_recipient in varchar2,
v_ccrecipient in varchar2,
v_subject in varchar2,
v_message in varchar2
)
AS
crlf VARCHAR2(2) := UTL_TCP.CRLF;
l_mailhost varchar2(255) := '10.138.0.15' ;
l_mail_conn utl_smtp.connection ;
v_header varchar2(1000);

BEGIN
--
-- Start the connection.
--
l_mail_conn := utl_smtp.open_connection(l_mailhost, 25) ;

v_header:= 'Date: '||TO_CHAR(SYSDATE,'dd Mon yy hh24:mi:ss')||crlf||
'From: '||v_sender||''||crlf||
'Subject: '||v_subject||crlf||
'To: '||v_recipient||crlf||
'CC: '||v_ccrecipient;


--
-- Handshake with the SMTP server
--
utl_smtp.helo(l_mail_conn, l_mailhost) ;
utl_smtp.mail(l_mail_conn, p_sender) ;
utl_smtp.rcpt(l_mail_conn, p_recipient ) ;
utl_smtp.open_data(l_mail_conn) ;


--
-- Write the header
--
utl_smtp.write_data(l_mail_conn, v_header);
utl_smtp.write_data(l_mail_conn, crlf||v_message ) ;
utl_smtp.close_data(l_mail_conn) ;
utl_smtp.quit(l_mail_conn );
--dbms_output.put_line('Message send to the user successfully') ;
END;


-----------------
CALL IT...
BEGIN
send_mail_alen(
'cocker@xxxxxxxxx',
'alen.cappelletti@xxxxxxxxxx',
'cocker@xxxxxxxxx,aaa@xxxxxxx',
'Oggetto del messaggio',
'saaaaaaaaaaaaaaaaaalve...');
END;

I have Notes client and the only field black is my message body.
Someone have a solution or a TIP?
