You've read the JavaMail FAQ, right? If not, please do now.
You've also found and tried the many sample programs that
come with JavaMail, right?
javax.mail.NoSuchProviderException: smtp
This error is often a result of not using mail.jar directly but instead extracting
the classes from mail.jar and adding them to your application. Don't do that.
If that's not what you did, I need more information about your environment,
such as your CLASSPATH setting.
