Thanks for the answers. Solution we are working on, supposed to provide access to some kind of a mail Dovecot archive exposed to a user as IMAP account in Outlook. The idea was to allow users to move messages between folders, but forbid direct drag-n-drop from the Exchange account.

I'd like to allow a user to move messages between his folders on Dovecot IMAP account, but prevent move/copy from different accounts (Exchange in particular). Outlook uses "xx UID COPY 1 folder" and then "xx UID STORE 1 +FLAGS (\Deleted \Seen)" for internal moves and "xx APPEND folder" for external ones. I tried to achieve this with ACL, but i (insert) seems to control both. Do I miss something? Should I look somewhere else?
That would also prevent users from saving messages to Drafts or Sent Messages. Unless of course this was a per-folder ACL.
Anyway .. nope, there's no way to do that. Why would you want it? You could create a plugin for that though.
