I'm wondering if this is a typical problem or if I have something amiss.  We have been running Spamfilter on a win2k machine for about 2 months and the bayesian filter does really well.  We had over 200,000 connections logged as of 2 days ago. 

We applied some Windows hotfixes 2 nights ago and restarted the server.  Everything restarted fine, but the inbound connections served and the good/spam email counts got reset to 0.  And it appears that the Bayesian filter is not working. 

I checked the corpus.ini file and it shows the large numbers I would expect, but the interface does not.  And the Bayesian filter is not working today (we have less than 5K of good/spam emails).  How can I avoid this in the future and is there a way to reset this now?

I'm still completely baffled about this problem.  I just upgraded to the newest release of SpamFilter and when it restarted, I am back to 0 in my email counts, which shuts off the bayesian filter again. 

I guess for me the Bayesian filter is what really makes this product work.  Whenever the Bayesian stops working my clients start complaining because it lets some spam through. 

Is there no way to reload the corpus and keep the bayesian going when you have to restart the application for server maintenance or whatever?

There must be a simple answer to this question.  Thanks in advance.

What counts exactly are you talking about? Are you refering to the 'Emails forwarded', 'Emails blocked' and 'Email Attempts' counters on the SF GUI?

If so by default they reset to 0 when you restart SF. I do not believe they effect the bayesian filter or the corpus database in anyway - its a seperate counter.

If you do not want these figures to reset when you restart SF, there is an option under the Settings > Configuration tab which reads "Remember Stats on restart". Ticking this will stop your counters from being reset.

If we are talking about the same thing, as I said before, I don't believe this setting or these counters have anything to do with the bayesian, so if you are having problems with that filter, I think you may have another issues not related to counters.

Well now that is interesting.  I had never seen the scrollbar for some reason and thus had never seen that checkbox to "remember stats on restart".  Thanks for that.

In my experience, with the two different times I've had to restart, the amount of spam coming through in the first day or so was vastly increased (prior to the 5K/5K bayesian kick-in). 

Can someone from LogSat verify what lyndonje stated above?  That those stats have nothing to do with the bayesian counters?

Thanks!

hookjd,

lyndonje is absolutely correct. The Bayesian stats are maintained separately, and will always be "remembered".

hookjd,

Just thought of something else... when you restart SF, your IP blacklist cache is reset - maybe that is what's increasing your spam after you restart?

Just a thought.

what % of probability do you guys have bayesian set too?  I have this feature currently turned off as i was getting a lot of false positives.  Any help would be greatly appreciated.  Thank you.

We have ours set to 52%.  We get very few false positives from this filter.
