Presuming that a missing tmp folder was the only issue, this issue would  
have no effect on the read/unread status of each message, and what was in  
reply to what. All of that metadata is tracked elsewhere.

courierimapuiddb and courierimapsubscribed exist only in a top level  
maildir. The other stuff exists in there and in every folder.

This happens automatically when one creates a new maildir using the  
maildirmake command.
