SMTP Routing - 19.Jul.2010 6:46:26 AM

Hi All,

Is it possible to specify how mail is routed externally based on SMTP domain regardless of where the users mailbox exists. For example, user1@test2003.com is always routed out of the SMTP server in site 1, users1@test2007.com is always routed out of the SMTP server in site 2.

The reason I ask is weíre currently going in the process of moving sites and migrating from Exchange 2003 to 2007.

The EX2003 environment exists in SITE1 and consists of a mailbox server and an OWA / SMTP server in the DMZ. Inbound and outbound mail goes via Postini.

Iíve built an EX2007 environment in a new site (SITE2). I have a mailbox server and a hub/client access server on the LAN. In the DMZ I have an EDGE server to forward SMTP to Postini.

Both environments are in the same AD and Exchange domain. Iíve moved my mailbox to the new site without any trouble and message routing is working fine however my external mail is still routing via the old 2003 SMTP server in SITE1.

Iíve registered a new domain name for testing purposes and will create an MX record which will point to the SMTP server in SITE2.

Thanks For you help

I guess you have specified a Smarthost in your Exchange 2003 in Site 1. If you remove that Smarthost entry, then your external email originating in Site 1 should go over the invisable Routing Group Connector to Exchange 2007 in Site 2 and then out to Postini.

Thanks Jesper, however what i'd like is for the existing 2003 mailboxes to continue routing traffic via site1 smtp and the new mailboxes in 2007 to route traffic over site2 smtp.

Thanks
