Solution: Your usb stick is (V)FAT formatted, and thus can't handle maildir folder names (nor can it handle permissions, which can cause many other problems). You have two choices. Either format your usb stick as ext2 (in which case you should be aware it can't be read on Windows OSes without installing additional software there) or create a tar file of all your mail, copy that to the stick and extract it to your new host.
