I see a potential problem for you: when you send a mail from your
linux machine to another machine in isbd.mynet, the envelope sender's
address will have isbd.demon.co.uk as the domain part.
Even worse: unless you fix all MUAs, the From: headers will have the
machine's name server2.isbd.mynet in the domain part.
I think the only way to succesfully manage your setup is to use the
mess822 package (from djb).

Currently I have:-
defaultdomain contains isbd.mynet
defaulthost contains isbd.demon.co.uk
locals contains isbd.demon.co.uk and server2.isbd.mynet
me contains isbd.demon.co.uk
plusdomain contains isbd.mynet
rcpthosts contains isbd.demon.co.uk and server2.isbd.mynet
