I've seen this reported before, but haven't seen a fix. I just installed 2.6.3.473 as a new install on Win2k3 Web edition, and the corpus folder is empty except for an empty queue folder. Other thread responses from admins seem to indicate that there should be more there. I even did the whole delete the folder and restart SF thing, and that didn't change anything. Consequently bayesian filtering does not work right now. Anyone have any ideas?

Learn new incoming emails is checked, but Bayesian Learning Status shows as inactive. Unchecking the box and saving then rechecking and saving again does not change the status. My SF installation has been running for several hours now and still nothing in the corpus folder except the empty queue folder.

What email address should I sent it to?

Form the 1st logfile you sent for the 4th, we can see that the timeframe it contains, from 22:03 to 23:57 (almost two hours) you only received one email. As mentioned in our first reply, that there needs to be a steady arrival of incoming emails to be processed for the Bayesian database to be built.

From the 2nd logfile from the following day instead, while the email traffic is slightly higher, it may not be enough to trigger the saving of the statistical database. The statistical data is cached in memory for a few minutes, and only on occasion is then saved to disk (to optimize performance). If there is not enough data in memory (in the order of an email every 4-5 minutes) that data is lost and not saved. The Bayesian filter really needs a steady flow of data for the statistical information to be built, and will not activate itself until at least 5000 spam and 5000 good emails are received. At the rate of an email every 5 minutes you can see that it will not be practical to use that filter.

Furthermore, from the SpamFilter.ini file you sent us, we see that your settings for the Bayesian filter are set to 100%, which, as stated in the GUI itself, indicates that the Bayesian filter is disabled. When disabled, the filter will not create/update the bayesian database.
