When I create a new user and click on ' Send test Email ' . It throws an exception ' Failed to send email titled "Mango test email" to "preeti.patankar@rediffmail.com". Message: "Mail server connection 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" ' .I open the Email settings in System settings but I dont know what I can enter in SMTP host and From address . Any help ? Also should I check the Enable TLS box ? What is it used for ?

Thanks Matthew . I am using Publisher feature from one Mango instance running on my machine to send some static data ( a = 10) to another Mango instance using HTTP Receiver datasource running on my machine . Here both the publisher and receiver are on same ip address. In HTTP sender properties I mention http://<ip address>:port/test/httpds . On HTTP Receiver side on clicking HTTP Receiver Listener I can see : Source : ip address Device id : Time : a= 10 b=10 . I want the same data in tabular format ( a jsp file) . How can I do it ? I can very well write a jsp page , but where in source code should I plug this page ? Also , data is received at httpds . Where is this httpds in source code ? Can I get it and simply put my jsp in its place ?
