Folks,

I got the following reply from Dmitriy <neo@???> :-

You can simply use NAT.
Also you should remove smartroute at all(simple smtp transport).
In case of Linux iptables:
iptables -t nat -A OUTPUT -p tcp --dport 25 -d ! 196.7.14.0/24 -j DNAT
--to-destination $smartroute:25
Every connection on tcp 25 port will be NAT`ed to smarthost except
connections to 196.7.14.0/24 subnet.
That is all and very simple :)

So simple it borders on off-topic :-)

Thank you, Dmitriy.
