You shouldn't need to use any code at all. If Exchange is configured
correctly, the internal addresses can be protected and outside users can send
e-mail from the Internet to your org by using smart hosts and the SMTP
connector:

Ok heres the story its kind of complex so let me explain it first
before I ask my question.
We have a local exchange server we use for in house email and my boss
will sometimes cc and forward stuff to people in our building and then
want to forward that stuff over to someone outside the building through
our outside email. So then someone gets that email it'll have addresses
only valid on our exchange server and people will reply to them and
have them sent back.
So what I want to do is write a script to change the cc addresses
to when ever a
message is sent to someone outside our exchange server. Is that
possible, and if so can someone give me a bit of code to work with?
