[Dovecot] IMAP fchown failed: Operation not permitted

[Juergen Obermann]

Hello,

today I switched from dovecot 1.1.17 to 1.2.6 and since then the following new error messages
appeared. To me they seems to be harmless, as I noticed no problems so far. But can I be sure?

This is a Solaris 9 system that acts as a NFS-Server for mailboxes in /var/mail
and home directories under automounter control in /home/group/user.

Thanks for any help.
