I'm a little confused by your wording, as I think you'll have to "download" the
mail from the remote server (that Mail.app doesn't like) in any case, but
assuming that I'm not misunderstanding your intention, there are at least two
solutions to pull IMAP mail to a local machine and keep the two mailboxes in sync:

1) Offlineimap <http://offlineimap.org/>
2) Dovecot's "dsync" utility <http://wiki2.dovecot.org/Tools/Dsync>

You can run either as a cron job to keep the two mailboxes synchronized.
Offlineimap can run as a daemon, as well.  Once you have the mail locally you
can run whatever IMAP server you want to serve it (dovecot is easy to
configure), or just use whatever MUA to access it directly.
