So, the murder really isn't intended to work like this.
Does UW-IMAPd even support proxy authentication?
If it does, *offhand*, provided you're not using internal mechanisms to
move the mailboxes (i.e. you are moving them by hand), I don't really see
a reason this won't work, but I'm not going to recommend it.
Do you really have so much data that it would take 2-3 days to move it?
