Re: [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: :0fw | /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.
