This is not good. I booted up Mail yesterday and found that more than a years worth of email has disappeared from my received email box. About three weeks of mail exists, but nothing older than that. Has anybody had this problem before? I'm actually afraid to start going after permissions and such because I don't see how it would actually help - if it works it works, if it doesn't it doesn't. So, I'm searching for advice and hopefully somebody has had the same problem and knows what to do.
