Question

Hi ,
How can i actually send to multiple ppl using utl_smtp ?
PROCEDURE send_test_message
IS
mailhost VARCHAR2(64) := 'mailhost.fictional-domain.com';
sender VARCHAR2(64) := '[email protected]';
recipient VARCHAR2(64) := '[email protected]';
mail_conn utl_smtp.connection;
BEGIN
mail_conn := utl_smtp.open_connection(mailhost, 25);
utl_smtp.helo(mail_conn, mailhost);
utl_smtp.mail(mail_conn, sender);
utl_smtp.rcpt(mail_conn, recipient);
-- If we had the message in a single string, we could collapse
-- open_data(), write_data(), and close_data() into a single call to data().
utl_smtp.open_data(mail_conn);
utl_smtp.write_data(mail_conn, 'This is a test message.' || chr(13));
utl_smtp.write_data(mail_conn, 'This is line 2.' || chr(13));
utl_smtp.close_data(mail_conn);
utl_smtp.quit(mail_conn);

You need to familiarise yourself with RFC821 - you'll find a copy at http://www.faqs.org/rfcs/rfc821.html
Do not confuse SMTP (an application protocol) with the way an e-mail looks. E.g. the TO and FROM fields in an e-mail can say anything and have no bearing on to whom the e-mail was send to, and from who it came.
Basically a "mail transaction" is a:
MAIL FROM - identifies the sender (can easily be spoofed)
RCPT TO - identifies a single recipient and can be repeated multiple times
DATA - submits the header and body of the e-mail
Read the RFC - it explains this in detail.
