Postbox (which is based on the Thunderbird code) notifies me every time a new email arrives. I have some message filters in place which move some messages automatically from the Inbox to a different folder. I don't want to be notified if such filtered messages arrive. I only want to be notified, for messages in my Inbox.
For Thundebird there is the FiltaQuilla extension which supports a "Do Not Notify" filter action, but I think it isn't supported in Postbox. Is there something similar for Postbox?
