Serious Mail problems
After upgrading to Mavericks, the following has happened with my Mail app :
1. Lost a couple of important folders wtih all messages in them
2. Flagged messages all messed up (wrong counts, for example)
3. Mail headers are there but there is no content in a number of messages
4. "Sent" folder is all messed up, some messages appear, others do not
Is there an immediate fix, so I can recover my previous Mail set up or do we need to wait for Apple to fix this ?
