No, actually no plug-in has been added.
I notice that at first, when my mails are not so many. it's better
Is there a way that you can move your old mails to another folder that you can 'surf' them in windows? (they won't appear in your MS Outlook)
One more question: if I want mails from senders of a specified group will be automatically placed in a specified folder in my inbox, what should I do? I tried 'rules' but I sucked, please help me!
