<itunes:email> element is missing
If an itunes:email element is not included, iTunes will send automated messages to the email associated with the iTunes Music Store account through which the podcast was submitted.
Consider including the itunes:owner element, along with a valid email address, immediately under the channel element.
An example follows:
<itunes:owner> <itunes:name>Your Name</itunes:name> <itunes:email>email@example.com</itunes:email> </itunes:owner>
