Access Denied sending emails to users in Child Domain

Hello All

I am fairly desperate on this and would appreciate any help.  Here is the setup.  

Parent domain: abc.com
Child domain: xyz.abd.com

Mailserver FQDN in Parent Domain: server1.abc.com
Mailserver FQDN in Child domain: server2.xyz.abc.com

The process used was as follows:

Child DC server setup and DCPrmo'd.  ForestPRep run on DC's in both Parent & Child.  Domainprep ther same.  Exchange installed, Exchange SP2 installed.  Connector configured.

I am able to create new users with email addresses in the child domain, can access information from the parent domain and vice versa.

The problem is that every time I send an email from a user in the parent domain to a user in the child domain, I get the following error:

The following recipient(s) cannot be reached:

      test 1 on 26/03/2007 14:15
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <server1.abc.com #5.7.1 smtp;550 5.7.1 <test1@abc.com>: Relay access denied>
 
Thanks in advance.

Jazz

Some version information would be nice. There are currently three major versions of Exchange being used, with one of those versions have two minor revisions. All of them have their own quirks.

Are you using smart hosts anywhere in the configuration?
Are you using routing groups?

Apologies,

I am running Windows 2003 with Exchange 2003 Enterprise SP2.
I am using smart hosts within the cvonfiguration and have ensured that both the servers are added using DNS for resolution.

Where are the smart hosts?
On the SMTP virtual servers or on SMTP Connectors?

If they are on the SMTP virtual servers then you need to remove them and replace them with SMTP Connectors.

It seems that I was a bit hasty on the it being resolved.  I can currently send/receive emails externally from the child domain, however I am unable to send/receive emails internally within the child domain and the child to parent and vice versa.  Can you please offer any additional help.

Thanks

Can you telnet to each server on port 25?

telnet ip.add.re.ss 25
telnet servername 25
telnet host.domain.com 25

If any of those fail then that can indicate a connection problem or name resolution problem.

Do you wish that you could place an email signature under a reply? Well, unfortunately, you can't. That great Exchange/Office 365 signature you've created will just appear at the bottom of an email chain. What a pain! Is there really no way to solve this? Well, there might be...
