You
bet.
I
have a bit of a custom / complicated system created.
I
have all mail caught by SA rejected and passed to a holding account - a regular
pop3 account which I do not check. I have Joe Savelberg's fabulous SA
script which I have hacked to process each message caught and re-write the
headers to include the SA score and reports. The script then moves the messages
to an IMAP account that I use to manually review the
messages.
I
have Outlook rules that assign the messages a category based on the spam
score 5,6,7,8,9,10+,15+,20+, etc which I then use to group preview the
messages. If the score is over 25 I don't normally even look at the
messages I just delete them.
I
then have a ham and spam folder in the IMAP review account. I can drag an
drop spam that gets by the filter and the same for ham that gets caught. I
then have a cron script that runs every 5 minutes and clears out these folders
via sa-learn. I also keep a copy of the ham and spam I feed to SA so that
if I ever need to kill the bayes database (coruption) I do not need to start
from scratch.
The
SA plug-in need to be changed so that the headers are changed by SA directly on
the front end and you need to be able to set a threshold to allow, review or
reject a message based on the spam score (.i.e. less than 10 allow, less than 25
forward to another address, more than 25 discard).

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.

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

bayes_learn_to_journal 0
bayes_auto_learn 0
bayes_min_ham_num

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?
