    can this be made to work:

    two domains on seperate subnets, each running a SBS 2003 and exchange server
    receiving email for the same external domain but for different users. For
    example is on one server and
    is on the other serve.

  2. Yes.

    Just for the sake of clarity, the SBS servers will need to be in separate
    domains.

    You also need to make sure that broadcasts for DHCP are not being forwarded
    between the 2 subnets.

    You can configure each domain to process mail for the same external domain
    the way you normally would in SBS (CEICW, default recipient policy, etc.).

    The mail would have to come in to one of the servers (whichever one the MX
    record pointed to) and then in the Messages tab of the properties of the
    Default SMTP Virtual Server of the one the mail first goes to, specify the
    IP or FQDN of the other SBS server. (You don't want to configure it that
    way on both servers because you could get ito a mail forwarding loop.)

    You can also configure conditional forwarders in the properties of the DNS
    server for each domain to point to the other SBS to resolve queries for its
    domain.

    excellent I was just finding some info on this, and as you said for the sake
    of clarity let me ask you this:

    you do mean the "forward all mail with unresolved recipients to host:" field
    correct?

    thanks!

    Chris.

  4. In a reliable and predictable manner? Just about.

    Would I do this? Absolutely not.

    I would run subdomains for the email: and


    Much easier to understand and manage.
