[Plugin: BulletProof Security] RSS Feed Header Problem with Mailchimp

Hello, I just started using BulletProof Secuirty after having a site get hacked and it seems to be doing the job to keep that from happening again. But I’ve noticed that now my rss to email campaigns in mailchimp no longer work. Mailchimp can’t recognize the feed any more. Any ideas on what to do to let the feed work for mailchimp but still be secure?
