I've had an email come through. The next thing I see Mail has automatically created a 'VIPs' box for it when it has NEVER done this before!!! The VIPs box has a star next to it. I've tride deleteing it, but that option is greyed out. I've looked online about deleting it and the various advice is to edit the 'VIPSenders.plist' file to remove all occurences of the sender, then relaunch Mail. Well I've done this and it makes no difference! Please help.
