Beginning yesterday (Nov 13) at about 17:00 eastern time, we have seen a drastic decrease in messages stopped by Reputation Filtering and an large increase in Spam Detected. The drop is from about 97% to 89%. Spam Detected has risen from 1.4% to 7.6%
Anyone else seeing this occur? We are using V5.1.2 of AsyncOS.

After 24 hours, the rejected message percent returned to their normal (excellent) levels.
