Error renaming folders with spaces

[mtrainer at cloud-free.com]

Hi All, 

I am getting frequent errors of the form below. In most
cases the path has spaces in it. 

 Oct 24 07:27:08 mailstore03 dovecot:
imap(sam at userdomain.com.au): Error:
rename(/home8/rs7-username/mail/xyzmortgages.com.au/sam/.Valuations -
ABC, /home8/rs7-username/mail/xyzmortgages.com.au/sam/.Valuations -
ABC/Subfolder) failed: Invalid argument 
The user home directories are
on NFSv3 and are the user attributes are stored in ldap. My config is
below.

Any ideas what is causing these errors?

Thanks 

Murray
