You can also accomplish the end goal with:

1) alias file entries that direct the local user address to the back 
end server (in which case, the sendmail server needs to be set up in a 
way that it thinks the destination mail domain is local)

2) a second milter, milter-ahead

(I'm currently using the alias method, but I'm considering using the 
md_check_against_smtp_server method; but for me it's not for an 
exchange server, it's for a communigate pro server; the only 
complication is that the communigate pro server is running on the same 
host as the sendmail service)
