I use 0.9.1 for Newsgroups/Mail as well, here are some comments.
1) all versions so far have "ghost" unread marks (ie, the thread icon
indicates unread, but there are no unread messages shown) I think mail
has the same problem sometimes as some message ARE there but don't show
up in the view.
2) only one "mail/news" connection at a time. If I perform a message
fetch while Moz. is refreshing a POP/News account, the message window
appears empty and has to wait for the refresh before displaying a message.
3) I think everybody has seen the mail folders not remembering sort
order in folders.
