[Dovecot] IMAPs and POP3s poxying

Hi All, I have a polotical situation at work that requires that I 
off-load mail access to a host other than the one our users have 
configured in their clients.  I don't have access to any of the 
switching or routing to our hosts, and there's only a 1 to 1 
relationship between the proxy I want to set up and the actual mail 
handler.  I was looking at the proxying Howto in the Wiki and was 
presented with an SQL server requirement to do user/ip address 
look-ups.  In my case, it will always be proxying the same host.  How 
would I configure Dovecot to proxy another single system without doing 
the SQL look-up?  Is there a port-forwarding solution that would work 
better (for POP3s and IMAPS)?  These are RedHat 5 hosts so Netfilter is 
fair game if the protocols allow.  Thanks,
-Jason
