This package includes RoundCube plugins that work with IndiMail

sauserprefs - Control Bogofilter settings from within Roundcube

markasjunk2 - Adds a new button to the mailbox toolbar to mark the selected messages as Junk/Not Junk, optionally detaching original messages from spam reports if the message is not junk and learning junk/not junk using various methods (bogo-learn, etc.)

iwebadmin - This is a plugin that adds tabs to the Roundcube settings page, allowing the user to set their vacation message or change their password. Behind the scenes, it logs in to iwbadmin as that user to make the changes. Both vacation and password tabs can be individually disabled.

Note: This screen-scrapes your iwebadmin installation, so currently only works if iwebadmin is in English.
