L2.APEWS.ORG False Positive #3

Here is another false positive, nobody else have any then? Strange, so much chat about the amount of errors generated by using Apews yet we're finding very few false positives. These that we have found to date are without using a whitelist and before any client side filtering.

Our client said that the email was in the spam folder but is in fact a daily newsletter aimed at folks in the travel business. Looking on the http://www.apews.org website, the IP address itself is not listed but the /24 is suggesting that there is a spammer with an IP address close to that of the newsletter. Further checking of Whois shows this IP address belong to Hetzner, a German hosting business, who in our experience have issues like this quite often.

  1. Good news, this IP address is no longer listed so that is one less false positive for the Admins to deal with.
