3.3. Rejection figures & statistics

In the two years that the service was in operation we rejected just over 200 million SPAM messages. This netted an average reduction in SPAM for the hosted users of 94%

In an average month, towards the end of the service's life, we rejected a total of over 10.5 million messages. That breaks down to the following sustained rejection rates:
