All of the directories and files were created by dovecot.  I didn't notice this in the logs until recently.  The files are stored on an NFS Raid if that makes any difference.

Sorry about the X's...  it is a client directory.  We support many 
domains and their privacy is paramount.   You are correct it is in the 
/cur directory.  I can LS all of directories without problems.  This 
user has 10+Gb in his mail box spread across 352 subscribed folders.  As 
for the logs it is always the directory, always the same error.
