Description

Scripts (based on LearnAsSpam) which allows users to interact with spamassassin rules simply by dropping mail in special folders of their mailbox (working only with imap).

  • Learn mail as spam
  • Learn mail as ham
  • Whitelist the sender so his mails won't be tagged as spam again

Requirements

You need to activate the Dag reposity before installing this contrib.

The following command will configure the Dag repository on SME Server. Dag After adding it to the database we have to update the changes to the configuration file:

signal-event yum-modify

Installation

First, download the contrib :

wget http://sme.firewall-services.com/downloads/learn/rpms/smeserver-learn-0.0.1-3.noarch.rpm

And then, install it :

yum --enablerepo=dag localinstall smeserver-learn-0.0.1-3.noarch.rpm

Don't forgot to configure db key according to your needs and expand config file.

Setup Bayesian Autolearning

You'll also have to setup Bayesian Autolearning as described in the Email page.

Automatic creation of folders

A script posted in the forum by Cactus [1] and sent to me by Amir Inbar can be used to create all folders (in skel for futures users and in the existings users too :

# create skellaton for new users :

mkdir -p /etc/e-smith/skel/user/Maildir/{.LearnAsHam/{cur,new,tmp},.LearnAsSpam/{cur,new,tmp},.LearnInWL/{cur,new,tmp}}

# create folders for existing users :

pushd /home/e-smith/files/users/; \
for u in `ls | grep -v admin`; \
do \
mkdir -p $u/Maildir/.LearnAsHam/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnAsHam/; \
mkdir -p $u/Maildir/.LearnAsSpam/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnAsSpam/; \
mkdir -p $u/Maildir/.LearnInWL/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnInWL/; \
done; \
popd

Thanks to them.
