If you're using SQL passdb, you could probably return host as either  
IPv4 or IPv6 depending on if %l or %r is an IPv4 or IPv6 address?  
Other than that I don't really see an easy way to handle this, because  
dovecot-auth has to be the one to decide if the proxying should be  
done or not, and it doesn't know all the IP addresses the Dovecot  
installation is listening on.
