Adding Additional Domains to Exchange 2003

I need some help with this....I have done this several times before, but for some reason, it is not working now.  I have an Exchange 2003 Server, that has been running fine for years.  During that time, I have added mail domains to it, and they worked fine.  I have recently added another new domain, but when I attempt to send mail to the new domain, I get the following error:

administrator@lqstrategies.com on 11/4/2006 7:25 PM
            There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.
            <ultimatemedium.com #5.5.0 smtp;554 <administrator@lqstrategies.com>: Relay access denied>

The domain has been added to the recipients policy, and it has updated all of the email addresses in AD Users and Computers...

I also tried running the Mail Setup Wizard, and followed the KB Article ID : 268838 for Configuring Exchange for Multiple Domains.

All of my other domains are still working, but this new one is still having a problem.  From dnsstuff dot com, if I run a mail test, I get the following response as well:

mail.lqstrategies.com. - 69.5.33.186  [Could not connect: Got an unknown RCPT TO response: 554 <administrator@lqstrategies.com>: Relay access denied

My MX records are all in place and properly setup.  I have logging turned on, but nothing shows up in the logs.  I send a message to an existing address, and CC the new address.  The existing is delivered and shows in the log, the new one gives me the error above, and nothing hits the log.

Any help would be greatly appreciated..

Thanks,  Parry Sands

Do you have anything between your exchange server and the internet?  Inparticular, a spam scanning device or software??

Failing that, have you ticked the new email address in the recipient policy?

Your MX records are not pointing at an exchange server.

They are pointing at BarrLantz.lantzquest.com

That is where you will need to start looking (or tell us what it is :))

Lol, no worries.

Glad to hear you got it sorted.

In future, try to remember this website -> http://www.zmailer.org/mxverify.html <- it will run a test on your domain and show you as it happens (very useful for figuring out what is playing up!)
