Can this be done?

Situation:

company has numerous small remote site WAN's with cable modem/routers. They have an exchange 2000 server for internal mail and an cable ISP that also handles internet email and hosts a domain. Both the Win 2000 domain name and internet domain are the same, SMTP works on the exchange server by settings found in MS KB319759.

Now a new temporary site has been set up (with it's own 2000 domain and exchange server) that has no access to cable so they're using DSL. SMTP mail works here by specifying the DSL SMTP server name and the POP3 works with the cable ISP settings. However, users cannot "reply to" emails from the cable internet email. They can type in the address and send. Error is "relaying denied"

So can the settings in KB319759 be modified to route the outgoing SMTP from the exchange server through the dsl SMTP server to the ISP hosting the company's internet email. I'm assuming that's why they get the "relaying denied" NDR on the "reply to"'s.

Thanks,
Scott
