Exchange 2010 Mail Routing

Hi Guys

Environment :
SBS2010, Exchange SP3
ISP hosts physical mailboxes that are popped every 10 minutes by the SBS2011 svr.

Site 1 hosts the SBS2011 server, 3km away, site 2 connects via OWA but SOME users POP mail directly from ISP.

Under accepted domains under hub transport, exchange is configured to accept the mail of both domains with domain A being authoritative and the default domain.

When an internal user sitting at site 1 sends a mail to a user sitting at site 2,{ the user at site 2 is downloading via pop, not OWA } the following error is returned to user at site 1 :

#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##

I know the error is generated because the user at site 2 isn't configured on the exchange server, but how can i get the exchange server to forward mail for receipients that don't exist on the server to the ISP?

Hope this makes sense.....

I'm not sure this is possible as your exchange server at site 1 will be configured as an authoritative server for the mail domain therefore will assume it handles all mail for that domain. Your best solution is to host all the mailboxes on the same Exchange server and have all users contact it to access the mailbox and have the ISP forward all mail to the server.  Your second option would be to move to cloud based email with something like Office365 and eliminate the need for an on-site exchange server but this is only viable if the number of users is low.

Thanks for the response.
My reason for asking the question is, i remember Exchange 2003 had an option to forward mail to a smarthost in the event that the user couldn't be resolved within the exchange organisation.
I was hoping exchange 2010 had the same thing.....

You can add the smarthost in the SBS Console> Home>configure a smarthost for internet mail.
Hope that helps,
Olaf
