I\'m using javamail to send mails from my appengine application. It works perfectly in the deployment, but I can\'t figure out how to do this using the development server. Whene
From the docs:
When an application running in the development server calls the Mail service to send an email message, the message is printed to the log. The Java development server does not send the email message.
So just check the logs when you intend to send mail, and make sure that it shows up there. No real mail will actually get sent.
