Attachments from being blocked

I have a client who is using dome shield that has their email on Attachments are blocked when dome is active, but when I change the DNS to OpenDNS, attachments work just fine. The categories I have blocked are Nudity, Pornography, Adult Content, Intimate Apparel & Swimwear, Personals & Dating, Illegal Drugs, Gambling, Tasteless & Offensive, Malware Related Sites, Illegal Software, Spam Related Sites, and Parked Sites.

Any ideas on what to do?

Thank you.
