I have filtering rules set up to send mailing lists to a seprate mailbox so that they don't clutter up my inbox. I still get a notification in the browser for every email. I filed a bug against roundcube notification plugin (https://github.com/roundcube/roundcubemail/issues/7890
) but they indicated that the problem is likely at my end, that the plugin is configured as "check_all_folders=true" which sends a notification for a new email anywhere rather than just the current mailbox/folder. Checking only the current folder would probably be more efficient too. Any chance that the notification plugin configuration could be adjusted?
