First, you'll want to fix these common mistakes, although they aren't the source of your problem.

Did you follow these instructions to add JavaMail to your project?

Try running your program outside of Eclipse, e.g., by packaging your application in a jar file and then using "java -cp SendMail.jar:javax.mail.jar firstpackage.SendMail".
