When an email that is received from a sender that has previously been marked as spam then Thunderbird activates the "beep" notification. When I tab to Thunderbird to see the email by then it has already been moved by Thunderbird to the Junk folder. This is quite frustrating as it unnecessarily interrupts workflow just to see that it was junk.

I would like it not to notify on messages that go to the Junk folder. Is there some way I can get this to work.
