The reason is explained in the text - "Message not accepted for policy reasons. See http://postmaster.yahoo.com/errors/postmaster-28.html"

In this case, the issue is probably that you're trying to use a Yahoo account to send from and (logically) Yahoo doesn't authorize your server to send from it. You may need to change your default email address and/or how you send email. (You should also take steps to setup something like SPF as mentioned in that link.)
