=== Zarafa Bayesian learning ===
This howto enables SpamAssasin Bayesian learning for [[:Zarafa]]
The DMZS script (LGPL) works over IMAP. It reads the mail from two folders (LearnAsSpam and LearnAsHam) and feeds it to SpamAssasin's sa-learn. This script is implemented here in a way that it makes use of public folders in Zarafa.
==== Installation ====
wget http://www.dmzs.com/tools/files/spam/DMZS-sa-learn.pl
mv DMZS-sa-learn.pl /usr/bin/
Create a user-account in Zarafa for reading the public spam-folders. Replace the <MyPassword> with a proper strong password.
zarafa-admin -c 'SpamAdmin' -p '<MyPassword>' -f 'Spam Administration Account' -e root@localhost
Now we'll edit the script and replace the Server, User and Password values. We will also have to replace two folder names throughout the script:
pico /usr/bin/DMZS-sa-learn.pl
Replace the values so it looks like below, replace <MyPassword> for the password you have chosen in a previous step:
my $imap = Mail::IMAPClient->new( Server=> '127.0.0.1:8143',
User => 'SpamAdmin',
Password => '<MyPassword>',
Debug => $debug);
Throughout the script (be aware of the quotes):
replace: 'spam' -> with: 'Public folders/LearnAsSpam'
replace: 'not-spam' -> with: 'Public folders/LearnAsHam'
remove: --showdots
Set proper rights on the script:
chmod 550 /usr/bin/DMZS-sa-learn.pl
Login to Zarafa with an account that has admin rights and make two new folders LearnAsSpam and LearnAsHam under: Public folder > Public folders.
Set the permissions (right-click folder > Properties > Permission-tab) on both these new folders to:
Spam administration account
* Folder visible
* Read items
* Edit items: all
* Delete items: all
Everyone (and/or other users/groups you've added at least need:)
* Folder visible
* Create items
* Edit items: none
* Delete items: none
{{Note box| Dropping mail in the public 'LearnAsHam' folder may pose a privacy problem if permissions are set less restrictive as shown above!}}
Create a new crontab fragment:
pico /etc/e-smith/templates/etc/crontab/91_SpamAssasinLearn
Add the following to the template (change the execution times to your own likings):
# Running the Spamassasin Bayesian SPAM learning script every hour from 8:00 to 22:00 during weekdays
* 8-22 * * 1-5 root /usr/bin/DMZS-sa-learn.pl
Make the new fragment active by expanding the template:
expand-template /etc/crontab
==== Configuration ====
Bayesian learning has to be enabled and configured in SME, you can read how to do this in: [[Email#Setup_Blacklists_.26_Bayesian_Autolearning | E-mail - Bayesian Autolearning]]
==== Usage ====
{{Warning box| All mail dropped in the LearnAsSpam and LearnAsHam folders will be automatically deleted !!}}
* Move/copy spam messages that are delivered to your Inbox to the public LearnAsSpam folder.
* COPY regular messages that end up in your Junk E-mail folder to the public LearnAsHam folder.
After the messages have been processed they will be deleted to save your valuable space.
