[courier-users] Unable to create dot-lock

[Bowie B. <Bowie_Bailey@BUC.com>]

My first attempt doesn't seem to have gone through, so I apologize if this
is a duplicate.

I am seeing this message on incoming emails to one of my users.  I cannot
find any permission problems in his directory.  Where can I look?  I need to
figure this out ASAP.  I've got over 200 message waiting for delivery to
this user at the moment.  I searched through the archives, but did not find
any suggestions other than maildir permissions.

Courier versions:
courier-0.46-1.2
courier-maildrop-0.46-1.2

I appreciate any suggestions.
