Who gave YAHOO permission to delete a particularly personal email?

Communications with my attorney both prior to and after the email in question still exist, as does the subject line of the email.





The entire text has been deleted -something impossible for me to do after it's been mailed. Only Yahoo themselves could take such action. You've illegally tampered with my personal content!





I darn well better get an answer!!

Yahoo owns your email. They can open, read, and delete your email and its contents without permission. They cannot however disclose some of the information held inside it with a 3rd party. If you want an email were nobody except you would have legal access to it, buy your own website/server and host your email on that.
