dovecot - Jan 2011 - How to enable COPY and APPEND commands separately

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?
Please help.

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.

Better to describe the actual *problem* and the end result you are
actually trying to achieve, rather than asking for help with a
pre-conceived solution that may or may not be appropriate or necessary...
