I have had a good read through this lot..
it looks like the transport_maps is the only bit that does near to what I need...
if i understand it correctly, this is done on a per domain level.. where I have lots all diverting to the other server,.. and its the other server resolving to the external ip.. so I would have to map all the domains over to the other server... also, some of them, are handled on this server, some on the other.. so I can't map a whole domain over, so I think this method won't work.. last issue, is I can't map it to an ip address.. where the internal machines are only find-able by their domain name - which will resolve to an external, or the ip addresses, external and internal, so short of setting up a second dns for the server, which resolves to an inetrnal ip, which isn't practical..
is there another angle to ask postfix to resolve the domain differently?
