What you are suggesting, is that the two machines will act as mail
servers along with the main server. This means they should be up 24/7,
AND that they should have the same anti-spam software as on the main
server, including any database with greylisting/blacklistingdata.

This may work, but I think the solution I suggest in another mail is
easier and also scales well in case it's not only machine1 and machine2,
but machine[001-999] with different operating systems. (Of course the
system on each machine should be configured to use user at domain.com
rather than user at machineXXX.domain.com as sender of email so as few
users as possible end up announcing and using the machine-address. For
simplicity, not security.)

Magni :)
sash is very good for you.
