−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.
