Hmm; with that in mind, I've hooked up gdb, and turned on the imap
protocol logging on the backends, and run through what it's doing when I
send a RENAME to the frontend.

It appears that the backend is receiving the RENAME command intact and
unchanged, and not any sort of XFER command. And therefore the reason it's
returning IMAP_PERMISSION_DENIED is because it's trying to rename to a
subfolder of a usermbox that doesn't exist on that backend.

Err... anyone any suggestions as to what I need to look at in my
configuration?

Cheers
