Is this interesting enough to incorporate, or make it a separate wiki entry and reference to it ?!

=== 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.
