I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the old behavior.
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.
