Exchange 2000 Use Smart Host or DNS depending on the sender's domain?
Posted on 2006-11-20
I have 2 domains hosted on a single Exchange 2000 server. Incoming mail works fine for both. Recently, one of these domains signed up with an anti spam service that requires that all outbound email from this domain (call it domain1.com) be sent through the anti spam company's smart host. This is easy to configure of course. However, the second domain on this server (domain2.com) also needs to send email outbound and so all of their outbound mail is being forwarded to the anti-spam smart host, which is dropping the mail since they are not signed up with the service. Is it possible to have Exchange use a different SMTP Virtual Server for each domain so that I could configure domain1.com to use the smart host and configure domain2.com to use DNS resolution? I tried looking at SMTP Connectors but those don't seem to help me since the "address space" that is configurable is for the receiving domain not the sending domain.
Thanks in advance for any assistance.
