Send Mail using JAVA

Question

Hi i would like to send a simple mail using java.. So i downloaded mail.jar and activation.jar file and i wrote simple program to send it.

My Simple mail program compiles successfully.. But when i run it shows the following error.

javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.ConnectException: Connection refused: connect

My doubt is how to find the SMTP server name for my PC? I searched in site but didnt get anything clearly..

Please make me to travel in a right direction...

With regards

Solution

You don't have to use SMTP server name for your PC, you have to use external email server, for example, gmail, yahoo, etc. You can set up mail server on you computer, but it is out of the question. In your case, you have to register new email in free mail system, and use it smtp server and port. You can google more about JavaMail API examples: cafeaulait, vipan

-1: TS needs to configure JavaMail to use the SMTP server of his ISP, not install a local SMTP server

If he tries to connect to localhost:25 he obviously don't want to sent emails from his ISP, but rather from his server or whatever. So your -1 is kind of random to me.

If you don't configure JavaMail correctly (as in: don't set the server) then it defaults to localhost

You might want to add some explanation and not just throw some code out there.
