You'll find a router for doing the relaying according to mx records
similar to this:
dnslookup:
debug_print = "R: dnslookup for $local_part@$domain"
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
same_domain_copy_routing = yes
no_more
You want to stick a smarthost router in front of that which delivers to
a specific host on certain conditions. The one below would route all
mail for foo@bar that originated from 123.123.123.123 to the mx
server "the.mx.server" directly:
smarthost:
debug_print = "R: smarhost for $local_part@$domain"
driver = manualroute
condition = ${if and{\
{eq{$sender_host_address}{123.123.123.123}}\
{eq{$local_part}{foo}}\
{eq{$domain}{bar}}\
}}
route_list = * "the.mx.server"
Hopefully that should give you a basis to work from.
