Sending mail from using utl_smtp error......

Question

Hi
When i try to send mail like as follows
DECLARE
v_connection UTL_SMTP.CONNECTION;
BEGIN
v_connection := UTL_SMTP.OPEN_CONNECTION('xxx.xxx.xxx.xxx',25);
UTL_SMTP.HELO(v_connection,'xxx.xxx.xxx.xxx');
UTL_SMTP.MAIL(v_connection,'[email protected]');
UTL_SMTP.RCPT(v_connection,'[email protected]');
UTL_SMTP.DATA(v_connection,'Sent From PL/SQL');
UTL_SMTP.QUIT(v_connection);
END;
I get the following error..
ERROR at line 1:
ORA-29278: SMTP transient error: 421 Service not available
ORA-06512: at "SYS.UTL_SMTP", line 17
ORA-06512: at "SYS.UTL_SMTP", line 96
ORA-06512: at "SYS.UTL_SMTP", line 138
ORA-06512: at line 4
if i send mail from outlook it goes...the configuration is like this
in mail properties general tab
email address : [email protected]
and i have to tick mark the "include this account when receiving mail or synchro" option
in servers tab
POP3 : xxx.xxx.xxx.xxx
smtp : xxx.xxx.xxx.xxx
and i have to tick the "My server requires authentication" option
and have to give the setting for that also
ie. log on using account : [email protected]
     password: xxxxxx
How to Correct it ?

Answer 1

i am on the same platform and in same account..... and PL/SQL UTL_SMTP gets a connection plus SMTP error, while telnet cannot even get a connection. A very weird one. Not sure what the problem can be.
Worse case, forget telnet and do all your troubleshooting using UTL_SMTP.. with liberal usage of DBMS_OUTPUT. :-)
regd. the connection from my xp client it is
connecting to the telnet server on server, but when i
tri to connect to the ISP's smtp address it throws
the errorNot that strange. You're likely going through a proxy of sorts of to reach the ISP mail server. Besides, to send mail you should be able to use your company's SMTP server as it should route Internet e-mail out to the net automatically.
In fact, many SMTP servers will not allow you to relay via them. E.g. if you connect from domain 1 to SMTP server on domain 2, and you submit an e-mail to be delivered to domain 3, the domain 2 server will tell you to take a hike. It will only accept mail that is destined for its own domain or originating from its own domain.
Reason for this is spam. Open relays are one of the prime reasons for having billions of spam mails being transmitted.
The correct method will be for you on domain 1 to connect to domain 1's SMTP server and submit an e-mail to be delivered to domain 3. That will be accepted and delivered. Using domain 2 as an intermediate agent to act as a relay, is/should not be accepted by all SMTP servers. (your SMTP server should get blacklisted/blackholed if it has an open relay)
