After a little more digging I found that dovecot 2.2 implements the IMAP
MOVE extension from RFC 6851 which my clients also support. Before that,
a copy with delete was used, explaining the different behavior. I also
see MOVE announced as a capability, so my clients use it. So, no config
issue, just a new feature.
