Urgent - Mail from Oracle

Question

Dear friends,
I want 2 send mail from Oracle PL/SQL . I have used the
following code to send mail.
create or replace PROCEDURE send_mail_1 (sender IN VARCHAR2,
recipient IN VARCHAR2,
message IN VARCHAR2)
IS
mailhost VARCHAR2(30) := 'mailhost.mydomain.com';
smtp_error EXCEPTION;
mail_conn utl_tcp.connection;
PROCEDURE smtp_command(command IN VARCHAR2,
ok IN VARCHAR2 DEFAULT '250')
IS
response varchar2(3);
x number;
BEGIN
x:= utl_tcp.write_line(mail_conn, command);
response := substr(utl_tcp.get_line(mail_conn), 1, 3);
IF (response <> ok) THEN
RAISE smtp_error;
END IF;
END;
BEGIN
mail_conn := utl_tcp.open_connection(mailhost, 25);
smtp_command('HELO ' || mailhost);
smtp_command('MAIL FROM: ' || sender);
smtp_command('RCPT TO: ' || recipient);
smtp_command('DATA', '354');
smtp_command(message);
smtp_command('QUIT', '221');
utl_tcp.close_connection(mail_conn);
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(SQLERRM);
END;
I am able to successfuly create the procedure. But while
executing the procedure I got the following error "ORA-29540:
class oracle/plsql/net/TCPConnection does not exist".
I have used the following format while I tried executing the
procedure
execute send_mail_1
('[email protected]','[email protected]','Test')
Are the above parameters are correct?. Further should I need to
change 'mailhost.mydomain.com' string value?- If yes what value
should be given there?
mailhost VARCHAR2(30) := 'mailhost.mydomain.com';
Kindly help me in this regards.
Thanks in advance

Something like:
Create or Replace  Procedure Send_Reminder IS
  CURSOR cur_reminders_needed IS
  SELECT *
  FROM mytable
  where trunc(reminder_date) = trunc(sysdate)
  FOR UPDATE OF reminder_date;
BEGIN
  For rec in cur_reminders_needed LOOP
    my_mail_pkg.send_emal(rec.stuff_from_my_table);
    UPDATE mytable set reminder_date = reminder_date+rec.reminder_increment
    WHERE CURRENT OF cur_reminders_needed;
  END LOOP;
  COMMIT;
END;Then use dbms_job.submit to create a job that runs send_reminders every day.
Then take a nap, Oracle will do everything else.
