The key part of your request is answered by using IP addrs in square brackets, 
which will not require DNS MX or A lookups.  So, add something like:

foo@[10.0.0.55]

...to the ~/.forward file of root or wherever the mail is going to now.  Yes, 
you could put this in the aliases, or even use a mailertable to redirect all 
local mail to the other system.
