M-Switch Anti-Spam False Negative Rate Graph Update

As mentioned in previous posts (Blog post May 9th 08 and Blog post May 14th 08) we have been paying particular attention to the False negative rate of the copy of M-Switch Anti-Spam running here at Isode's offices. We wrote a whitepaper on our findings:

“Measuring the False Negative Rate for Isode’s M-Switch Anti-Spam.”

The whitepaper included graphs showing the daily quantities of Spam we received and the daily False Negative rate going back over 4 months (up to 30th April). We always intended to keep these graphs up to date so that they would continue to track M-Switch's performance and today we've updated them to include May's figures.

We will continue to update these graphs, at the end of each month, so that they always show current data.
