CRM114 Training via SquirrelMail

Download

The crm_trainer SquirrelMail plugin
(does not include the Training scripts and procmail recipes)
The Master training script
(runs as root and executes the User script once per user)
The User training script
(performs message training and redelivery)
The Helper script
(used when training cannot be performed)
The procmail recipe

Download the plugin to your SquirrelMail plugins directory.
tar -xvzf crm_trainer*.gz
cd crm_trainer
cp config.php.sample config.php
Edit config.php if you want to change the names of the mail folders used for training Spam and Nonspam
Edit constants.php if you are using OSBF_Lua
cd ../../config
./conf.pl
Choose Option #8 and add the crm_trainer to the set of installed plugins
Save and quit

Copy the training and helper scripts to a suitable directory such as /usr/local/bin
Set owner of the Master training script to root and make executable by owner
Set owner of the User training and Helper scripts to root and make executable by any user
Edit the scripts and set the configuration parameters as appropriate
Add the Master training script to the root crontab. Frequency is up to you. For my small site, I use every two minutes.
Remember, you have to run the script twice; once to train Spam and once for Nonspam
/usr/local/bin/trainAll.crm114 --spam; /usr/local/bin/trainAll.crm114 --nonspam

Refer to the CRM114 documentation for instructions on setting up a basic Spam filtering system
I strongly suggest that you turn on the text_cache feature.
Make sure that each user account has a "Spam" mail folder (or whatever name you decide to use)
Install the included procmail recipe to ensure that incoming messages are trained and delivered to the correct mail folder.
If you use a name other than "Spam" for the Spam folder, be sure to edit the recipe before deploying it.
SquirrelMail will create training folders for each user upon first use.
