Alex,

You are absolutely right. I missed the imapd.conf option 'allowusermoves:
1'.

Do you have that set? With that option set, I can move top level user
mailboxes:

zek.olp.net> create user/test
zek.olp.net> rename user/test user/test2
zek.olp.net> create user/cyrus.test
zek.olp.net> rename user/cyrus.test user/test.cyrus
renamemailbox: Permission denied
zek.olp.net> setacl user/cyrus.test cyrus all
zek.olp.net> rename user/cyrus.test user/test.cyrus
zek.olp.net> lm
user/cyrus.test (\HasNoChildren)   user/dwhite/test (\HasNoChildren)  
user/dwhite (\HasChildren)         user/test.cyrus (\HasNoChildren)   
user/dwhite/spam (\HasNoChildren)  user/test2 (\HasNoChildren)        

So I'm able to move toplevel mailboxes with the allowusermoves set to one,
but I'm not allowed to move the (presumably) top level mailbox of
user/cyrus.test until I give the cyrus user permissions on it.

On 2.3.16, I get:

zek.olp.net> create user/test
zek.olp.net> rename user/test user/test2
zek.olp.net> create user/cyrus.test
zek.olp.net> rename user/cyrus.test user/test.cyrus
renamemailbox: Permission denied
zek.olp.net> setacl user/cyrus.test cyrus all
zek.olp.net> rename user/cyrus.test user/test.cyrus
renamemailbox: System I/O error

I'll take a closer look at why.
