Hi!

I understand Dixit's suggestion, and is exactly what I was looking for when I browsed this forum:

We want the externall app to be notified when new mail arrives; that works fine (thanks for this great extension!)
but, as soon as the new mail is read, we would like a second notification to be sent to the app (with a special or custom argument, perhaps?), so that any continuous effect (sound / led on, etc.) can be switched off.

I have an app that turns the mail led led on or off, depending on the argument. I would like it to turn the led on at the same time as the little envelope icon appears on the system tray. Then, when I check the first message, the envelope disappears, and I would then like to be able to send another notification to switch the led off.

Thanks again for the great extension. If you could just implement this I believe it would become perfect!
