Local email needs to be sent via ISP's smtp server
Posted on 2007-08-02
Due to unusual ISP reliability issues, it is difficult to use the Exchange server as it was intented. What I have set up is a smart host where email is sent to the clients web domain smtp server (not their isp). This is working well for email outside of their domain but not working at all for local addresses. Since our outside folks are using the web hosts pop3 to gather their email, anything send internally is ending up in their exchange email box and not being sent out to the web hosts mail server.
The question is this: When I send an email to someone within the clients domain, is there a way to force exchange to send it to the webhosts mailserver instead of holding it locally? I believe I've seen messages to that effect but haven't had any luck locating them.
As background, DNS is working correctly on the server. I have the smart host set to go to the ip address (in brackets; [xxx.xxx.xxx.xxx]) in case of a DNS issue. In the address space there is a single '*'. The local bridgehead is the SBS server. I have outbound security set to authenticate. The webhost server is a Linux box.
Thanks in advance for the assistance with this knotty problem.
