[Dovecot] FETCH for mailbox INBOX UID 5003 got too little data: 5369 vs 38919

[Adam McDougall]

This happened a while back, I was running 1.1rc3 up until today so I have no idea
if it would have an effect.  Sorry if its something that has been fixed.  The 
error below was repeated many many times, I deleted the index so the user would
stop getting disconnected (although I didn't hear any complaints).  I have not 
seen this happen repeatedly in this manner to any other user yet.
