Over the past month, I've noticed that SpamSieve's effectiveness at catching spam has dropped considerably. I've been training it for nearly four months now, and it has many thousands of messages to work with.
Originally, it was catching about 90% of incoming spam. Now that's down to around 60-70%. On some days, I get as much spam in my inbox as the software catches. I've heard reports that this is due to the nature of the filter concept that software like this uses. I'm wondering if others are seeing the same trend, and if pruning the corpus or some other technique would be effective in returning it to its formally effective self! --- Scott T.
