We have Exchange Server 2007 using our domain ddd.com.

We created an isolated network with a firewall/gateway and installed a DC and Exchange Server 2010 using a demo/test domain (ddd.loc).

We opened all the needed ports in the firewall (10.10.2.88) to the Exchange Server 2010.

In our main Domain Controller (10.10.2.3) we defined the domain ddd.loc with IP 10.10.2.88 (firewalls). We also we defined MX records to the same IP (10.10.2.88)

We did that so when we send email from my email me@ddd.com it will go to the Exchange Server 2010.

Anyways, all the pings test from to any servers are OK.

But we are not able to send or receive emails. Between these Exchange Servers we can not send any email from the 2010 to any email in general (emails are pending).

Also, in Exchange 2007 we are getting error #550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##

no idea what your question is –  pablo Mar 17 '11 at 7:51
    
but when we test we get error - care to share? –  Ben Pilbrow Mar 17 '11 at 8:07
    
Sometimes, when we know what test you actually did and what errors you actually got, we can help you fix the problem straight away. Without that, it could be anything from a firewall problem to low flying alien spacecraft interfering with your wiring. –  RobM Mar 17 '11 at 8:14
    
we have 2 exchange server we want them to send emails to each other based on the email domain, id I send email with my outlook to test@dddddddd.loc it will send it directly to the other exchange server (IP) and the other way around –  Data-Base Mar 17 '11 at 8:18

Dont completely understand the whole question but.

Sending an email to the 2010 exchange will entail you creating DNS pointer in you production DNS Server (e.g. your Domain Controller)

how to make it so that the 2010 will send email directly to the 2007

think you want to send email from the dddd.local through the 2007 server this will envolve routing the SMTP to 10.10.2.11 << Link explaining the process

You will though need to make sure your firewall is configured correctly

If you could phase the question better ill do my best to answer if the answers are not what you expected

Thanks I did rewrite my question :-) –  Data-Base Mar 17 '11 at 8:51
    
Are there DNS pointers in your DC's pointing to the other domains? - E.G. ddd.local on ddd.com's dns server point to 10.0.0.1? –  Trozz Mar 24 '11 at 16:16
    
it points to (10.10.2.88) and the dns port is open to 10.0.0.1 –  Data-Base Mar 25 '11 at 10:13
    
also the MX records point to (10.10.2.88) and the SMTP port is open to 10.0.0.11 –  Data-Base Mar 25 '11 at 10:46
    
Are you using it as NAT? because unless you are using NAT and forwarding the ports to the correct machine it will fail... if you are not using NAT try pinging 10.0.0.1 or 10.0.0.11 from the live network e.g. 10.10.2.3 –  Trozz Mar 29 '11 at 8:14
