MaxCDN is working, but RSS feed images are not being served from the CDN

Hi,

On one of our sites, we send emails out through MailChimp once a new blog post happens. However, the RSS feed is pointing to the non-CDN-ed images. Have I misconfigured something?

Site:

RSS:
http://www.eatboutique.com/feed/

Thanks,

Don
