Custom Link to RSS Feed -- "cannot be accessed to anonymous users"

Hey There,

I created a script to create RSS feeds for our website and update them via cron. The script creates an actual file that contains the feed data that lives in the http address space -- for example: http:www.raystedman.org/podcast/ephesians.rss . We would like to include these podcasts in the sitemap.xml.

I tried to add a custom link for the podcast files. I received the following error message:

•The custom link podcast/ephesians.rss is either invalid or it cannot be accessed by anonymous users.

The podcasts are available to anonymous users so I'm not sure what is happening here.
