Thunderbird is giving me notifications from all senders and there doesn't seem to be an option to not get notifications from particular senders - or from things that've been given a rule to go into a different folder. I only want to be receiving notifications from e-mails that remain in the inbox (or other folders) AFTER filtering rules have been applied. Is there anything I should be doing within the thunderbird application itself, or is this something that requires an add-on?
