[Samba] Viruses and the list

I was forced to put a filter (spambayes) on my list (Lm_sensors) to keep
out most of the garbage. It's really helped a ton, and I can scan the
'spam' to make sure nothing real got blocked from the rest of the
recipients of the list.
It's pretty easy (I used procmail, spambayes, and a large amount of spam
and normal mail to train it). It's also easy to refine the training as
time goes on.
In a nutshell, for my main mail server I created a database:
hammiefilter.py -n -d/mypathtothedatabase/hammie.db
Then trained it:
nice mboxtrain.py -d/mypathtothedatabase/hammie.db -g
/pathtomyGOODmail.mbox -s /pathtomyBADmail.mbox
(You can run the line above as many times as you want with just -g or
just -s or multiples to keep appending to the database)
And then I added the rule to the top of /etc/procmailrc:
| /pathtothebins/hammiefilter.py -d /mypathtothedatabase/hammie.db
Finally, the emails will now contain a new header (nothing gets blocked
or modified other than the addition of this header):
X-Spambayes-Classification: ham; 0.01
ham/unsure/spam refers to the general classification, and 0.00-1.00
refers to the percentage likelihood that it is spam. From there, you
can filter/forward/etc. in procmail scripts or on the client end, or
whatever you want to do. You can even create multiple databases to do
levels of classification (e.g. percentage chance that it is a virus, or
that it is from your parole officer, etc.) and use formail to rename the
header after each scan.
I hope this helps.
