I've noticed that quite a few menus and such have a Thunderbird look to them...maybe just laid out a bit differently.
This leads me to be concerned about the adaptive junk mail process. The menu for setting it up in the account's properties looks exactly like the Thunderbird menus. I don't know if the "behind-the-scenes" process is different, but this is VERY disconcerting to me.
Thunderbird's adaptive process has turned out to be crap. No matter how many times I tell it specific emails ARE NOT junk, it still sends them to the Junk folder. I'm just wondering if I'm going to have the same issue with Postbox...if it has copied TB's process. This is the main reason I'm leaving TB. Do I have to give up on PB, too, and go to The Bat!?
