Send mail to exchange server with TLS

Question

Hi,
last month I enabled an oracle wallet TDE for creating encription for TS.
Today, development team needs to send mail to exchange server with TLS.
So I found this procedure on oracle support Doc ID 1323140.1
My question is, can I use the same wallet to send mails from db?
The Oracle Database  11.2.0.3
Or I need to implement a different type of wallet with certificate?
Is there, in this case,  a procedure step by step?
I have never implemented that and I'm very confused....
Thanks in advanced

Hi, I have implemented a new wallet with certificates (for test SMTP.gmail.com) and i'm tryied to use this procedure:
DECLARE
mailhost VARCHAR2(64) := 'smtp.mydomain.it';
sender VARCHAR2(64) := '[email protected]';
recipient VARCHAR2(64) := '[email protected]';
wallet_pwd VARCHAR2(64) := 'welcome1';
wallet_loc VARCHAR2(64) := 'file:/etc/ORACLE/FRMSSYST/SMTP/';
user_name VARCHAR2(64) := 'HDC021319';  -- alias for '[email protected]'
user_pwd VARCHAR2(64) := 'password';  -- password of [email protected]
mail_connection utl_smtp.connection;
BEGIN
-- Make a secure connection using the SSL port configured with your SMTP server
-- Note: The sample code here uses the default of 465 but check your SMTP server settings
mail_connection := utl_smtp.open_connection(
host => mailhost,
port => 25,
wallet_path => wallet_loc,
wallet_password => wallet_pwd,
secure_connection_before_smtp => FALSE);
-- Call the Auth procedure to authorized a user for access to the mail server
-- Schemes should be set appropriatelty for your mail server
-- See the UTL_SMTP documentation for a list of constants and meanings
UTL_SMTP.helo(mail_connection, mailhost);
UTL_SMTP.STARTTLS(mail_connection);
UTL_SMTP.AUTH(
c => mail_connection,
username => user_name,
password => user_pwd,
schemes => 'LOGIN');
-- Set up and make the the basic smtp calls to send a test email
utl_smtp.helo(mail_connection, mailhost);
utl_smtp.mail(mail_connection, sender);
utl_smtp.rcpt(mail_connection, recipient);
utl_smtp.open_data(mail_connection);
utl_smtp.write_data(mail_connection, 'This is a test message using SSL with SMTP.' || chr(13));
utl_smtp.write_data(mail_connection, 'This test requires an Oracle Wallet be properly configured.' || chr(13));
utl_smtp.close_data(mail_connection);
utl_smtp.quit(mail_connection);
END;
This procedure, works fine if I try to send an email to smtp.gmail.com (I tried first with gmail with appropriate certificates), but now, when I try to send an email to the local enterprise Exchange server  I get this error:
ERROR at line 1:
ORA-29279: SMTP permanent error: 503 5.5.2 Send hello first
ORA-06512: at "SYS.UTL_SMTP", line 54
