Need help in designing mail server

[Santosh Ganapa]

Hello friends,

I am designing an application using jsp.In that application, I need to provide users with facility to send and recieve emails.Please guide me how to use JavaMail APIs.
I have one doubt that, Is it necessary to check mail system only after deploying the application on the hosting server.???

First of all, you don't plan to write your own mail server, right? Presumably you get access to a mail server with your hosting contract.

As for how to use JavaMail, I suggest starting with the JavaMail tutorial. (Google keywords: "Javamail tutorial")

Is it necessary to check mail system only after deploying the application on the hosting server.???

I have no idea what you mean by this. Perhaps you could describe the problem which led you to ask it?

I don't want to write mail server on my own. But how can I test whether my application (written based out of the tutorial) will work fine or not? Need more details on testing and implementation point of view.
