Well that problem has not reoccurred yet today but I've made the change 
you suggest anyway.

Now we're on to:
dovecot: 2009-06-25 18:50:15 Error: IMAP(strr): fchown() failed with 
file /home/local/strr/Maildir/index/Archive/.junk/dovecot.index.log: 
Operation not permitted
dovecot: 2009-06-25 18:54:15 Error: IMAP(strr): fchown() failed with 
file /home/local/strr/Maildir/index/Archive/.junk/dovecot.index.log: 
Operation not permitted

Bizarrely the similarly placed .junk-2008 folder has no problems 
creating the 'strr' specific index files.

I've tried deleting the folders / files and chowning/chmodding until I'm 
blue in the face and since the umask change they are now created with a 
umask of 0007 ... but the error keeps coming back in the logs.

Let me know if you need more information

Cheers,
Stu.
