We have serveral locations running exchange. Each location has the = domain @location.bitor.com.=20 We host our mail @bitor.com with an ISP, all mail for @bitor.com is = delivered to the ISP mail servers which is then forwarded to the = respective @location.bitor.com. Our exchange servers are connected to each other using IMS connectors.=20 When we send mail from one location to another, the mail bypasses the = ISP mail server as our directory uses the respective @location.bitor.com = email address. We want our mail to go to the ISP server and then get = forwarded as we do not want to run POP3 servers so that users who travel = can check mail directly from the ISP. Any indication as to how to resolve this would be greatly appreciated.
