I believe the two routing group solution is working. I won't know for sure until SiteB starts to receive Internet email, but everything else looks good.

Question - what would happen in the event the SMTP Internet proxy mis-delivered email to SiteA when the recipients mailbox is hosted in SiteB? Would SiteA then route it internally?

Thanks, again, James!

Option 1. Use no routing groups. If your site links is fairly fast you can keep in one same routing group, no connectors. Email sent by a user, it's respective server will send directly to internet. Email sent to user on another exchange server in another site, Exchange will route internally. Make sure you have MX records for both servers and reverse DNS records

So, within the default routing group created by SBS (SiteA was an SBS install, SiteB is plain Win/Exch), how would the connectors be configured?

Any information in AD or as a recipient policy that needs to be set?

Internet MX records will resolve to the independent hosted SMTP proxy. Are you referring to those MX records or internally for DNS as a dependency for routing internal email?

Option 2. Create two routing groups per site, create routing group connects for internal mail delivery between sites. Create SMTP connectors in each routing group with scope of routing group only. This will ensure that servers in each site will send out through it's respective smtp connector in it's own routing group\site.

A total of four routing groups, then? How would the connectors be configured in this option?

Thanks, James.

AD SiteA - - Exchange/Windows 2003
AD SiteB - - Exchange/Windows 2003 part of SiteA AD and ORG

SiteB is new, and just promoted the single server as a DC GC and installed Exchange into SiteA org.

Inbound Internet email will be delivered to each respective site by an independently hosted SMTP proxy. Internal email should be routed between the two sites (they are connected via dedicated VPN tunnel). Outbound Internet email should be delivered from each respective site direct to the Internet. I.E. SiteA should not send SiteB's outbound Internet email; and vis versa.

I am trying to understand how to configure the Exchange routing/connectors to meet this requirement.

Any assistance would be greatly appreciated.
