Many of you have noticed over the past week or so that we have been seeing a higher than normal amount of spam slip through the filters and make it to users’ in-boxes. We have been in contact with MailFoundry and they have told us that there was an issue with their system that takes messages from the reported spam feed and injects them into the rule creation engine, thus updating the spam definitions. This has caused reported spam to not get put into the engine definitions in a timely manner, leading to an increase in non-filtered spam over the last week or so.
Reportedly this is looking better today, but the MailFoundry developers are monitoring the situation to see if any additional adjustment is necessary. For those who have reported this increase in spam to our support, please monitor the situation over the next few days and let us know if the amount of spam slipping through begins to reduce.
