I had thought that it used the SmartFilter XL list (like v6 before it) but I've now come across a situation where a site being accessed is categorised as Webmail, yet the trusted source web site database query tells me that the site is not categorised at all.
I've got the rule enabled that allows uncategorised sites, it's bypassing that rule because as far as the MWG7 is concerned the site IS categorised as webmail... how?
I'll PM you the site details. According to the trusted source web query all of the databases have the site as uncategorised for www. (although mail. is categorised as Webmail as you'd expect).
All I can assume is I've got a rule wrong (but can't see how/where) or the 126.96.36.199 is somehow getting different database info.
