I don't know what all that gibberish means, but did you add your email address (from which you are
sending the email) to your Amazon.com account's
approved email list, on the
Manage Your Kindle page?
You have this free.kindle.com address already, as long as your Kindle is registered. My Kindle is registered as pidgeon92K3, so my email address for my Kindle is
pidgeon92K3@free.kindle.com.
