Re: Bayesian filtering is driving me nuts.

So, you do the training of the filters manually - by collecting a quantity of each in a mbox and processing it manually through the sa_learn utility?

I picked 1 for ham because I didn't get many and bayes won't kick-in until you have the minimum number of spam AND ham. I disabled auto learn because I had no control over the messages being added. I find the odd high scoring ham and didn't want these auto learned as spam.

Thanks Dan, I'll give this a try. Some stuff in here I didn't think of.

Question:

The min ham and spam numbers. Why did you pick these? Also, why not auto learn?

I'm hopeful this will really help with the spam detection. I use SpamSieve on my laptop and it has been hugely successful using the same technology.

It's ugly I agree.

Here is my SA config:

make a directory '.spamassassin' in /var/spool/post.office

drwxr-x--- 5 mta mail 170 Jun 24 15:02 .spamassassin

Edit your /etc/mail/spamassassin/local.cf:

## Misc

use_bayes 1
bayes_file_mode 0777
bayes_path /var/spool/post.office/.spamassassin/bayes
bayes_auto_expire 1
bayes_learn_to_journal 0
bayes_auto_learn 0
bayes_min_ham_num 1
bayes_min_spam_num 200

Ensure that your SA start-up script uses the '-u mta' option which runs SA as the same user as PO.

This set-up was the only way I have ever made it work properly. SA seems to pick a different location each time for the bayes
location unless you force / trick it.

I think I can improve my filtering big time with the Bayesian filtering for spamassassin. but i can't make it work. Here is what i
get from the log

Jun 24 14:48:38 mail spamd[2587]: debug: auto-learning failed: lock: 2587 cannot create tmp lockfile
/private/var/root/.spamassassin/.lock.mail.customer1st.com.2587 for /private/var/root/.spamassassin/.lock: Permission denied

I have run spamd as root. i have changed the permissions on the dir so that it is rw everywhere but still the same problem.

any suggestions?
