ORA-06512 errors (utl_mail)

Question

Hi,
I want to send mail using utl_mail.
I use Oracle 10g and prepare database go through this command:
CONN sys/password AS SYSDBA
@$ORACLE_HOME/rdbms/admin/utlmail.sql
@$ORACLE_HOME/rdbms/admin/prvtmail.plb
GRANT EXECUTE ON UTL_MAIL TO any_user;
ALTER SYSTEM SET smtp_out_server='smtp.gmail.com';
SHUTDOWN IMMEDIATE
STARTUP
Then I login to any_user and try send mail:
BEGIN
UTL_MAIL.send(sender => '[email protected]',
recipients => '[email protected]',
subject => 'This is a test :)',
message => 'Yeah, it worked! :)');
END;
But this give me this errors:
ERROR at line 1:
ORA-29279: SMTP permanent error: 530 5.7.0 Must issue a STARTTLS command first
f7sm989291nfh.25
ORA-06512: at "SYS.UTL_SMTP", line 21
ORA-06512: at "SYS.UTL_SMTP", line 99
ORA-06512: at "SYS.UTL_SMTP", line 222
ORA-06512: at "SYS.UTL_MAIL", line 407
ORA-06512: at "SYS.UTL_MAIL", line 594
ORA-06512: at line 2
Or I try this procedure (find on ask Tom site):
create or replace PROCEDURE send_mail (p_sender IN VARCHAR2, p_recipient IN VARCHAR2, p_message IN VARCHAR2) as
     l_mailhost VARCHAR2(255) := 'smtp.gmail.com';
     l_mail_conn utl_smtp.connection;
BEGIN
     l_mail_conn := utl_smtp.open_connection(l_mailhost, 465);
     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 );
     utl_smtp.write_data(l_mail_conn, p_message);
     utl_smtp.close_data(l_mail_conn );
     utl_smtp.quit(l_mail_conn);
end;
begin
send_mail( '[email protected]', '[email protected]', 'Hello :)' );
end;
But there SQL*Plus hang up and I must close application :/
Any suggestion for this??

The e-mail still needs to be delivered. A local SMTP server will still need to connect to another SMTP server in order to deliver the e-mail to the recipient.
If that local SMTP server can make that connection to that "other" SMTP server, why not simply do it from PL/SQL instead? A lot simpler than configuring something like sendmail as your local SMTP server.

Indeed an excellent site, but I doubt that UTL_SMTP will be deprecated. Just like UTL_SMTP did not deprecate UTL_TCP.
Each one builds on the other, providing a higher level abstraction interface. UTL_TCP is needed to talk tcp to the SMTP server. UTL_SMTP uses that to talk SMTP over tcp. UTL_MAIL needs SMTP to deliver auto formatted Mime bodies as e-mail.
Maybe what PSOUG implied that from a programming perspective, you should deprecate using UTL_SMTP and instead use the much easier abstraction API called UTL_MAIL.
It does not make a lot of sense for application code to use UTL_SMTP directly, given the higher level mail API provided by UTL_MAIL.
At the same time, it make sense for one to write your own UTL_MAIL wrapper, extend the abilities of UTL_MAIL (such as supporting multiple attachments, etc) and use UTL_SMTP to perform the delivery.
