FCC to imap folders

[mah@everybody.org (Mark A. Hershberger)]

I'd like to know how to Fcc: to an IMAP folder.

Currently, I have the following added to message-send-hook:

(message-add-header (concat "Fcc: " (expand-file-name
                                     "~/mail/sent-mail")))

The documentation for message says that I message-fcc-handler-function
takes care of the Fcc: and is set to `message-outout' by default.

I skimmed over the source, but didn't see anything right off.

What do message-fcc-handler-function and my Fcc: field need to be set
to to save to an IMAP mail folder?
