> To clarify on this, I do get the sound beep and the system tray icon for "1 unread message"

Do you get the popup notification for new messages in a POP account which get moved by filters on arrival? If you do not get the popup notification, then you do see the same issue as I described in Comment 10.

>  I wrote in comment #2 that for whatever folders (two) it gets called when the email comes in in the scenario described, the flags are: "Once it's SentMail, and then Trash."

I do not understand that sentence. As described in Comment 10, the integer flags value of the folder in question would be helpful. Set a breakpoint here:

and watch `folder.flags` and `folder.prettyName` (enter these two in the "Watch Expression" area of the debugger). This should tell you which folder is currently being processed and what its flags value is. Single stepping through the code (F10) shows you what the function is doing for your folder.
