Give sendmail a mailertable entry. From memory (will prolly be wrong so
double-check me):
* smtp:exchange.blah.net
should work. this'll make sendmail divert everything that it gets to
exchange.blah.net.
another way to do it would be to put a tcp proxy on the linux box. this'd
listen on port 25 on the proxy box and open up a link to port 25 on the
exchange box whenever a connection happens.
yet another way to do it would be with NAT but you'd need 2.4.x for that.
Hope this helps.
