Hi Bernard-
I have a few questions:
- What does your policy look like?
- What URL categories are you trying to block?
- Have you looked at the event logs and see how the site was classified
- Have you checked checked BrightCloud and SenderBase and see if the site is properly classified:
http://www.brightcloud.com/tools/url-ip-lookup.php
http://www.senderbase.org/
I hope this helps!
Thank you for rating helpful posts!
