[Dovecot] fchown() error with Public Folders

[Stephen Carville]

I was able to get public folders to work with a dedicated account for
the hierarchy and ACL's for individual users.

I have location defined so that each user has a local index and control files

location = maildir:/usr/mail/public/cs/mail:CONTROL=~/Maildir/CS:INDEX=~/Maildir/CS

Now i am seeing the folliwing error in the logs.

dovecot: IMAP(stephen): fchown() failed with file
/home/stephen/Maildir/CS/.Incoming/dovecot.index.log: Operation not
permitted

As I understand it, dovecot runs as root but the the IMAP process that
servicers the request runs as the user so naturally the fchown()
fails.  However it seems the file is never even created.  It there
someting I need to do to get this to work?

I am using 1.1.7
