This is what most of us use MS for. ;-)

That's really the task of your MTA. I know Sendmail supports LDAP
lookups but I think there's beta code for something similar in MS also.
Some people on this list extract all addresses from Exchange and export
it to a file Sendmail can check. There's all kinds of setups but you
should start more basic and build on it.

I don't use MS as a gateway, I have it between my DMZ gateways and the
Exchange battery but most here run MS on their gateways. It's really the
MTA that is the gateway, MS doesn't care where it is placed and it
doesn't touch the config of your MTA.

I would recommend setting up a test system and send mail from it to a
Yahoo account. That way you can test all settings and stuff. That's what
I did.
