Try taking the physical mbox file, putting it on a client machine with 
Thunderbird in the <profile>Mail/Local Folders/ directory, then allow 
Thunderbird to open/rewrite/save it back out. Then stick it back on your 
server and see if that fixes it...

Or, maybe even do the above, create a *new* folder and drag&drop all the 
messages from folder A into folder B (so a fresh-write would have to 
happen), then put folder B back onto the server named as the original. 
TBird reads/writes regular old normal mbox files.

Just some ideas, hth.
