Too bad and sorry to hear that. Toaster was a nice little add-on.
The last comment related to Zimbra Notifier 3.0.7 from Habitech which I assume is not part of the Zimbra project. That product does not work at all (at least for me).
This thread started with a discussion about the Toaster add-on that I believe is/was provided by the Zimbra project.
