We have our Exch 2003 server on the domain, which is for example i.com. we had a second domain with email that was working which i just moved to another company we changed the MX record Now if I send email from gmail to the second domain it works, but if i send an email from my domain to that domain it fails.
How do i make sure our exch is not sending them locally but sending them out to the internet? I can provide more info if needed

Check your Recipient Policies and make sure that your server does not have a policy that tells Exchange it is authoritative for the domain.

You should remove the old domain if Exchange no longer handles mail for the domain.

Once removed from the Recipient Policies - you have to manually remove any email addresses added to each user account !!

Yep - lose the domain if it is no longer managed by your server and that will tell Exchange that it is not responsible for handling mail for the domain and it will then send it externally.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Nope - it's pretty much instant.

Delete it and then remove the email addresses associated with the domain on the user accounts and then try to send the domain an email.  It should be sent externally.

No - you need to remove it from AD Users & Computers - from each account with an address added, which could be every account!

Also - if you send a test message, make sure you don't pull the complete address from the Autocomplete entry that Outlook might offer you as that will remember the internal Exchange user account and try to send the message internally.

Type in the full email address and then send.

If the email address is still in AD - you will have problems.  Please delete the email address from the user you tested and then create a new email, type in the full address manually and then fill in the Subject and something like Test in the body and hot send.

It should then get delivered externally.

Now i get the error from the front end exch

            The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.
            <mail.AD #5.1.1>

No problems.  If that doesn't resolve the issue - please restart the Exchange System Attendant service and the Exchange Routing Engine service.

I would imagine it is down to Recipient Filtering on the Front End server.

Sorry - the "Simple Mail Transfer Protocol Service".  It's not near the Exchange Services - it's lower down the list of services.

There is no need to restart the Information Store.

You don't need to forward unresolved mail as your server is no longer authoritative for the domain!

Did you remove the domain name or just untick it from the Recipient Policy?

Unticking it will only stop it from generating email addresses when you create an account.

Is the domain name Bold or normal?

If it is bold - you need to select another domain name and make that one Primary - then you can delete it - if not bold - highlight the domain name and remove it (click Remove button).

If the email address exists in Exchange it will not help the situation.  If your server no longer manages mail for the domain I would be deleting every single trace of the old addresses on each account and distribution group etc.
