You could do this with postfix. Setup the "MAIN" server as a postfix
mail gateway, and use your local server as the imap server. The
messages will arrive at the "MAIN" server that your MX record points to
(where they could be spam/virus filtered) and then would be immediately
passed to the local network server (where users could access them via
pop/imap). I don't know if this is what you are looking for as users
would need access to the local network to even read their mail, and you
would only have one persistent copy of the hosted mail (instead of the
office being a secondary backup), but it would help to increase speed.
