I'm using Thunderbird 3.1RC1. The mail directory in the profile had smart mailboxes, smart mailboxes-1 and smart mailboxes-2 directories. I deleted them, started Thunderbird, and switched to smart folders, which are now called "Unified folders".
I noticed that my profile now has a smart mailboxes-1 directory. Why doesn't it follow the normal naming conventions? Am I going to get several versions of it again? if so, why does that occur?
