I'm seeing an issue on Kerio Connect 8.0 on Mac servers where if a user marks a message as spam and then clicks the not spam button, the bayes statistics do not update for ham. I've used to used this method to quickly train the bayes db with messages that should be ham but that may score too high to be automatically learned as such. I've also relied on this method to quickly get bayes up to the required 200 messages learned as spam and ham before it will be used to modify scores.

If a message does score low enough, it is being learned as ham and the statistics are updating to reflect that. It's user trained ham that appears to not get learned. I've tried using the Kerio web interface and have also tried moving messages from the Junk mail box. In each case, the spam log shows that the message has been requested to be learned as ham but the numbers shown under bayesian filter statistics do not change.

I'm also seeing the following although I'm not certain it indicates why Kerio isn't learning my messages as ham.

If you have a message in your inbox, then you mark it as Spam, then you mark it as Ham, it will not count towards your score. As I see it, it will just remove the learned entry you made before.

For example if your statistics were

Spam=15, Ham=15

Then you get a mail in your inbox which does not count towards Ham (because the score was too high), your statistics are still

Spam=15, Ham=15

Now you mark that message as Spam. Your score will be

Spam=16, Ham=15

Now you mark the same message as Ham, your score will be

Spam=15, Ham=15

It will deduct the learned Spam, but not increase Ham.
