no inbound emails on SBS 2003 Exchange

We can send email but unable to receive email.
New SBS 2003 Exchange installation

-full internet name can be found and  
-OWA works just inside the network

MS domain collins.local
Internet domain is different.

Few emails bounced back, the ones doing it:
"550 5.7.1 Unable to relay for john@collinsand.net"

Any help is welcome....

It sounds like exchange is not configured to accept emails for your external address.

have a look at http://www.petri.co.il/configure_exchange_2000_2003_to_receive_email_for_other_domains.htm#

and add the domain collinsand.net

Cheers
Andrew

on a side note.
I looked up the MX record for collinsand.net and it does not exist. Is this the external Email domain?

As a thought i looked up collins.net and that does exist. Is that you?

An SMTP test to Administrator@collins.net worked fine.

the recipient policy are ok.

internal domain is collins.local internet domain is collinsandcompany.net

-From outside
.ping to the full domain name and it translate correctly
.telnet could not open connection to the host on port 2 (I did try to the ip address same result

-From inside (open the name of the server only) telent is able to open connection.

An important detail is that we have a proxy, now mcafee (but mxlogic in the past) I did open a case with them just in case, waiting response. Since mxlogic console offer the tools to test connectivity from the proxy to the host and find no problem.

Hi,
i just tried to a telnet to your gateway (collinsandcompany.net.inbound10.mxlogic.net) and it was successful. that means that McAfee(MXLOGIC) accepted the message and should try to forward it to you.

Without knowing the external IP address of your router and the port that you have shifted (if you are) your SMTP to I am unable to test further.

-From outside
.ping to the full domain name and it translate correctly
.telnet could not open connection to the host on port 2 (I did try to the ip address same result
I was able to "telnet collinsandcompany.net.inbound10.mxlogic.net 25" successfully.
Was it a typo above where you state port 2

Cheers

Hello,
yes, it was a typo and I did open a case with MXlogic just in case.
For some reason only part of the restore got into the exchange configuration so I'll have to review everything.

The only special on the config is that the internal domains and the internet domain are different AND the inbound is coming from MXlogic.

The dns table (record A and mx) are ok and ip translation is ok as well.

ok, it is working now, I just shutdown the server and turn it back on and it is accepting inbound. My guess is that even the config was ok it was accepting only the .local domain and not the internet one (both are different).
