Roundcube/Plugin/markasjunk - Mark-as-junk

Beschreibung

Adds the sender's email address to the blacklist, or run a command such as sa_learn.

• Shipped with Roundcube
• README (detailed drivers howto)

With this nice plugin the end user can add the sender's email address to the blacklist, or run a command such as sa_learn.

Create the config file from the template

cp config.inc.php.dist config.inc.php

sa_blacklist driver

Requires spamassassin-user-prefs (sauserprefs) plugin and Spamassassin Userprefs

Clicking on the button "Mark as Junk" creates a new "Black_list from" record in the database and moves the message in the Junk folder eventually marking it as read. Clicking on the button "Mark as Ham" creates a record "White_list from" in the database and restores the message in the Inbox.

To use the plugin with the driver sa_blacklist:

$config['markasjunk_learning_driver'] = 'sa_blacklist';

---

The following cmd_learn driver should not be used anymore, as we already setup a cronjob for training our bayesian filter and reporting our spam (more info here).

cmd_learn driver

This driver calls an external command to process the message. You can use it to call sa_learn and spamassassin in cascade. Be aware that you have to eventually remove shell_exec from disable_functions in your php.ini so that php can execute shell commands.

Prepare the shell script with the commands to run when clicking on the "Mark as junk" button. Save as /usr/local/bin/teach_spam.sh the following code

cat > /usr/local/bin/teach_spam.sh << __EOF__
#!/bin/bash
/usr/local/bin/sa-learn --spam --username=$1 $2 >> /var/log/spamassassin/sa_learn.log 2>&1​
/usr/local/bin/spamassassin --nocreate-prefs --report < $2 >> /var/log/spamassassin/spamassassin.log 2>&1
__EOF__

The first command feeds the mail to SpamAssassin, allowing it to 'learn' what signs are likely to mean spam. The latter one reports the mail as spam to Razor, Pyzor and Spamcop.

Now prepare the shell script with the commands to run when clicking on the "Mark as ham" button. Save as /usr/local/bin/revoke_spam.sh the following code

cat > /usr/local/bin/revoke_spam.sh << __EOF__
#!/bin/bash
/usr/local/bin/sa-learn --ham --username=$1 $2 >> /var/log/spamassassin/sa_learn.log 2>&1​
/usr/local/bin/spamassassin --nocreate-prefs --revoke < $2 >> /var/log/spamassassin/spamassassin.log 2>&1
__EOF__

Again, the first command feeds the mail to SpamAssassin, allowing it to 'learn' which signs are likely to mean ham. The latter one revoke the report to Razor. Apparently the revocation is not possible with Pyzor and Spamcop (but I didn't look deeply in my log yet).

Provide execute priviledges to the newly created scripts

chmod +x /usr/local/bin/teach_spam.sh /usr/local/bin/revoke_spam.sh

Set these options

$config['markasjunk_learning_driver'] = 'cmd_learn';
$config['markasjunk_spam_cmd'] = '/usr/local/bin/teach_spam.sh %u %f';
$config['markasjunk_ham_cmd'] = '/usr/local/bin/revoke_spam.sh %u %f';

Setup che logrotate for the above log files:

cat > /etc/logrotate.d/spam_reports << __EOF__
/var/log/spamassassin/spamassassin.log /var/log/spamassassin/sa_learn.log {
su root apache
rotate 5
daily
missingok
notifempty
delaycompress
create 664 root apache 
sharedscripts
}
__EOF__

You have to assign +w priviledges to apache in the log dir and to Razor's identity-* files, as Roundcube is runned by apache:

chgrp apache /var/log/spamassassin
chmod g+w /var/log/spamassassin
chgrp apache /etc/mail/spamassassin/.razor/identity-*
chmod 640 /etc/mail/spamassassin/.razor/identity-*
chmod 644 /etc/mail/spamassassin/.razor/razor-agent.log

multi_driver driver

• Original driver for the ancient markasjunk2 plugin
• multi_driver plugin patched for markasjunk (diff here)

It is possible to run multiple drivers when marking a message as spam/ham. I patched the original version by Philip Weir to work with markasjunk and run sa_blacklist followed by cmd_learn.

Install as follows:

cd /var/www/roundcube/plugins/markasjunk/drivers
wget https://notes.sagredo.eu/files/qmail/patches/roundcube/markasjunk-multi_driver/multi_driver.txt
mv multi_driver.txt multi_driver.php

Set the correct driver in the config file:

$config['markasjunk_learning_driver'] = 'multi_driver';

Be aware that the markasjunk's multi_driver driver, when enabled, seems to prevent the display of the attached images. Why this driver is related to this problem is a mistery. Any comment on this will be welcome.
