| − | 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.
