Installation#9. Can DansGuardian be integrated with real-time external/remote verification services (similar to the RBL lists for email)?
Usually performance considerations make external URL verification impractical. If you think your badly outdated blacklists sometimes cause problems, upgrade your subscription to revise your blacklists more frequently. An exception to the rule of avoiding external services is to incorporate OpenDNS into your DNS lookups. Some of its protections -for example those against phishing attacks- can be usefully combined with DansGuardian without introducing significant performance or maintenance problems.
