dovecot - Jul 2007 - 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

Dovecot isn't really designed for that kind of a proxying, so you can't
avoid it.

Well, it sounds like you need generic TCP proxying which doesn't need to
know about the used protocol at all.

Googleing tcp proxy found this as the first hit:
