Hello everyone, I'm using this code to connect to Yahoo! smtp mail server and send an email, first I am initiating a handshake to authenticate my connection, then I am sending the email, I am currently getting the error ora-06502.

Note: I tried both ports 25 and 587.
Also, please note that the PC I'm working on is connected to the internet but I still have to open the OC4J instanc for the form to run.


declare -- variable to hold the smtp server connection
v_smtp_connection utl_smtp.connection;
-- variable to hold the contents of the email message
v_smtp_host VARCHAR2(100) DEFAULT 'smtp.mail.yahoo.com';
-- variable to hold the smtp port
v_smtp_port NUMBER DEFAULT 587;


begin
-- establish the connection to the smtp server
v_smtp_connection := utl_smtp.open_connection('smtp.mail.yahoo.com', 587);

-- perform a handshake with the smtp server
utl_smtp.helo(v_smtp_connection, 'smtp.mail.yahoo.com');

utl_smtp.command(v_smtp_connection, 'AUTH LOGIN');
utl_smtp.command(v_smtp_connection, utl_encode.base64_encode(utl_raw.cast_to_raw('mail@yahoo.com')));
utl_smtp.command(v_smtp_connection, utl_encode.base64_encode(utl_raw.cast_to_raw('MYpassword')));

-- set the 'from' address of the message
utl_smtp.mail(v_smtp_connection, 'mail@yahoo.com');

-- add the recipient to the message
utl_smtp.rcpt(v_smtp_connection, 'mail@gmail.com');

-- open the message for writing
utl_smtp.open_data(v_smtp_connection);

-- populate the message with the build up message header and body
utl_smtp.write_data(v_smtp_connection,'lolz');

-- close the message for writing
utl_smtp.close_data(v_smtp_connection);

-- end the connection to the smtp server
utl_smtp.quit(v_smtp_connection);

end;


ANY help is greatly appreciated. Obviously I don't have an SMTP server but I should be fine connected to Yahoo! Mail and it doesn't require SSL.

Thanks in advance.
