Exchange 2010 add a sub domain smtp address with another smtp outbound relay

    Question

  • I

    We need, for testing pourpose, create a sub domain SMTP address to our Exchange 2010

    For exaple we have the SMTP domain @test.com and we need to add @1.test.com

    We have also to configure a relay SMTP address different from the default and use only for the mailboxes @1.test.com

    How can we make it?

  • You will need to configure an accepted domain.  If Exchange will host all the mailboxes for the domain, then make the type "Authoritative", otherwise choose "InternalRelay" or "ExternalRelay" as appropriate.

    You can then add the e-mail addresses to any mailboxes you want.

    If you're forwarding mail for that domain outside of Exchange, then create a send connector for the domain pointing to the other server's smart host.

    I don't understand what you're asking here:

  • If the accepted domain is Authoritative then it won't relay addresses not in the GAL anywhere.  If you want that behavior, change it to InternalRelay or create mail contacts for all recipients external to Exchange.

    If you have to relay mail outside of Exchange instead of using mail contacts, then you'd create a send connector with an address space of "1.test.com" and a smart host with the FQDN or IP address of the host where the mail is to be relayed.

  • Hi Ed

    The mailboxes are inside the domain so we do an Authoritative accepted Domain whit the new SMTP.

    For the outbond SMTP traffic we have to use  a different sender connector only for the @1.test.com mailboxes that point at a different SMTP relay, but we don't know how configure it.

    Thanks
