  I didn't notice that changed it only for index files. This should really

  http://hg.dovecot.org/dovecot/rev/b2c14c07dcb2
  
Applied to 1.1, I'll see how it goes.

However I just logged in with it and saw one I've been seeing occasionally:

Oct 28 11:01:40 gribble dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.gribble.97159.dc6633e16f47011d) 
failed: Operation not permitted
