Is there a way to proxy based on the host name the client has configured in his/her email client? (Like Apache VirtualHosts)

I doubt it; the virtual name is not part of the IMAP protocol as it is in HTTP. The IMAP server is not told which hostname was mapped to its IP.

You'll either have to add the @domain, or perhaps multi-home your host, remap one of your domains to the new IP, and add another running instance of dovecot to listen on that interface.
