I would like to install this plugin, which could help with set filters. I downloaded, changed name and added directory to /etc/roundcube/plugins: Code: [email protected]:/etc/roundcube/plugins# ls acl database_attachments enigma http_authentication markasjunk2 password squirrelmail_usercopy additional_message_headers dovecot-impersonate filters jqueryui newmail_notifier sauserprefs zipdownload compose-addressbook emoticons help managesieve new_user_identity sieverules but it does not work. Besides, when I log into roundcube and click About in left upper corner, I can see installed plugins list (I also attach screenshot): archive, filesystem_attachments, jqueryui and zipdownload. I have also /usr/share/roundcube/plugins path but in plugin's guide does not exists any information about put something to this path. Does anybody know how to make this plugin work?
