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


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.

Subject: [ExchangeList] Two sites - Outbound Internet email independent


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.
