It looks like the server at mr2.uky.edu is blocking/filtering her e-mail.
As per RFC1893:

  X.7.1 Delivery not authorized, message refused

  The sender is not authorized to send to the destination.
  This can be the result of per-host or per-recipient
  filtering. This memo does not discuss the merits of any
  such filtering, but provides a mechanism to report such.
  This is useful only as a permanent error.

Seeing as your list is hosted at uky.edu, you should talk to the e-mail
administrators there and see if this is the case and what can be done to
resolve it.

The simple solution is to tell your subscriber to change her subscribed
e-mail address to an online 'freemail' account (Yahoo, GMail, etc.) but
some people may not want to do this.
