1.11.2 2018-04-12 06:40 UTC



The features of this plugin have been integrated into the markasjunk plugin in the Roundcube core (v1.4+), via pull request 6504. This plugin is now obsolete.

This plugin adds "mark as spam" or "mark as not spam" button to the message menu.

Inspiration for this plugin was taken from: Thomas Bruederli - original Roundcube Mark As Junk plugin

When not in the Junk mailbox: Messages are moved into the Junk mailbox and marked as read

When in the Junk mailbox: The buttons are changed to "mark as not spam" or "this message is not spam" and the message is moved to the Inbox

The Learning Driver

The learning driver allows you to perform additional processing on each message marked as spam/ham. A driver must contain a class named markasjunk2_{driver file name}. The class must contain 3 functions:

spam: This function should take 2 arguments: an array of UIDs of message(s) being marked as spam, the name of the mailbox containing those messages

ham: This function should take 2 arguments: an array of UIDs of message(s) being marked as ham, the name of the mailbox containing those messages

init: Optional, this function should take 0 arguments. eg: allows drivers to add JS to the page to control which of the spam/ham options are displayed An example driver is available to show how to use the JS events

Several drivers are provided by default they are:

cmd_learn: This driver calls an external command (for example salearn) to process the message

dir_learn: This driver places a copy of the message in a predefined folder, for example to allow for processing later

email_learn: This driver emails the message either as an attachment or directly to a set address. This driver requires Roundcube 1.4 or above.

sa_blacklist: This driver adds the sender address of a spam message to the users blacklist (or whitelist of ham messages) Requires SAUserPrefs plugin

amavis_blacklist: This driver adds the sender address of a spam message to the users blacklist (or whitelist of ham messages) Requires Amacube plugin. Driver by Der-Jan

sa_detach: If the message is a Spamassassin spam report with the original email attached then this is detached and saved in the Inbox, the spam report is deleted

edit_headers: Edit the message headers. Headers are edited using preg_replace.

WARNING: Be sure to match the entire header line, including the name of the header, and include the ^ and $ and test carefully before use on real messages. This driver alters the message source

Running multiple drivers

WARNING: This is very dangerous please always test carefully. Run multiple drivers at your own risk! It may be safer to create one driver that does everything you want.

It is possible to run multiple drivers when marking a message as spam/ham. For example running sa_blacklist followed by cmd_learn or edit_headers and cmd_learn. An example multi-driver is available. This is a starting point only, it requires modification for individual cases.

Spam learning commands
