How much is 'a *lot* more code'? > Either way, I don't really see why they would list a 2tld, or a free > sub-domain hoster, but not some of their hosted stuff. For precisely the cases like the one I stumbled across. Because some of their subdomains can be whitehats. The DNS technology covers such cases just fine (a wildcard, along with more specific exceptions). > DBL lists $spammer.spaces.live.com, but they won't list spaces.live.com. > This is the same situation with a different sub-domain hoster. Let's modify this example a bit: spammer.live.com blacklisted, but live.com not. And our plugin strips out the first label, querying for live.com given an URL http://spammer.live.com/, and we miss a hit. What I'm driving at is - it doesn't take much stretching to come across cases of FP or FN due to the fact that URIDNSBL plugin can easily split/strip domain names differently than DBL does. -- Configure bugmail: https://issues.apache.org/SpamAssassin/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
