disable notifications for certain programs?

Question

I'm using Ubuntu 12.04 with Xfce-4. I would like to use thunderbird's own notification, but activating that turns into 3 messages per new mail:

• one from Thunderbird with mail info
• one general with mail info
• one just saying "You have new mail" and "no default action".

Is it possible to exclude Thunderbird from the general notification? I would like to keep the other programs calling xfce4-notifyd.

From its source page here, Run xfce4-notifyd-config to display the settings dialog. There aren't any other settings you can tune; if you do not see it in the settings dialog, it's not changeable.
