Cannot send mails

fly_fisher — Thu, 04 Jul 2002 10:36:45 GMT

Hi all,

I have an application in HPUX 11.0 that sends lots of mails using sendmail. But I'm obtaining the next errors:

Wed Jul 03 12:57:37 CEST 2002. Work 5. ERROR : Error sending MDN:
javax.mail.SendFailedException: Sen
ding failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host:
localhost, port: 25;
nested exception is:
java.net.SocketException: errno: 0, error: Error 0 for fd: 16

If I telnet localhost on port 25 I can enter sendmail.

Does anybody know what is happening?

I send you the sendmail.cf.

Thank you very much for all your help,

Best Regards.

Nothing springs to mind, but I would recommend taking a look at /var/adm/syslog/mail.log. That may give you some pointers...

when you did a telnet to your SMTP server port 25 , could you send mail successfully to the recipient ?

Are you going via a proxy server , if so consult who ever looks after this on how to send an external mail address via your lan proxy

Hi,

Can you send us the output of this command

# sendmail -v abc@xyz.com < /etc/hosts

It looks like your mail goes to the relay machine to be sent. According to your attached file, the relay machine is
"mbtpmta"

I think you should: telnet mbtpmta 25
not, localhost 25

You have to be able to see the relay host
on port 25.
