OVH mail servers got blocked around 15:00 CET today as well. It's rather disappointing that there's no action from MBAM for over 12 hours on these posts (none that I know of anyway). I thought they were applauded for their fast reaction to new threats. Not to false positives, it seems.
These are all shared servers or mail servers from OVH in France. While there might be some malware on them (these are shared hosting servers after all), it's not proportional to blacklist their IP as there will be many many legitimate sites on them (some of mine amongst them). Regards, Sander.
