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. Regards, Martin
