Ok I am confused.

What is "group job related email"? What does it have to do with sorting and threading?

I don't understand your confusion. My last post seems pretty clear to me. Threading only seems to group emails as to the day they were first threaded. Not today. So whenever the thread started ie. last month, last year, last week. That's when the email is going to get listed/posted in the menu. Well who the hell is going to sort through a thousand emails before they get to the threaded email that arrived today? Who's even going to know that a threaded email arrived today? I'm calling it "group", because the person who sent the first one called it that and everyone who responds to that subject line is being threaded. It was called a group because it's messaging only a few co-workers from different departments that need to stay in contact. Threading is a big horses-ass as a complete failure. Even trying to "unthread", they still don't show up as today's mail in "today's" in the date part of the menulist. At this point I'd like to completely turn it off and be able to look at what arrived today in the today area of the date column. How do I get this undone?
