[Neeraj jain]

When i am sending the mail to PostCast Server i am getting the Exception

javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: localhost
, port: 25;
nested exception is:
java.net.ConnectException: Connection refused: connect
at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at MsgSend.main(MsgSend.java:24)


while the same program runs fine on other system .........please tell me wat is the problem i also disabled the firewall and antivirus still not working for me

Obviously your application or application server is configured to use localhost as SMTP gateway. But "connection refused" usually means that there is no socket opened for localhost on port 25, i.e. there is no SMTP server running.

I guess on the other systems for which it works as expected there is a local SMTP server running or the application server is configured to use another existing SMTP server.

So please tell me what is the solution

[Marco Ehrentreich]

From your description we have no idea what your software does or how the whole setup looks. So I can only guess what could be a solution.

1.) The easiest solution would probably be to install an SMTP server on the machine where you want to run the application. On Linux this is usually done out of the box, so I suspect you are not running on Linux. Unfortunately I don't what free SMTP servers you could use for Windows, but I'm sure there will be some.

2.) The second solution could be to configure another SMTP server in your application server. But this would require an existing SMTP which allows to relay mails from your application. Of course I don't know if you have such an existing SMTP gateway at hand. The actual configuration depends on the application server used but you should find the relevant information in its documentation.

can you tell me the good SMTP server and please don't tell some complex ones as i am in an initiative stage

[Ulf Dittmer]

Why don't you run the code on that other machine that already has a mail server up and running? You don't really want to run a mail server on your desktop machine anyway, or do you?
