NDR being delivered along with incoming mail

[niallo32]

I have an Exchange 2000 SP3 Exchange Server. All mail is being sent & received without fail. Two users have an alternate address under their Exchange properties in Active Directory, e.g user@domain2.com.

On Friday, one of the users starting receiving the message below, along with every incoming email. The incoming email was sent to user@domain1.com and not to the address or domain referenced in the mail below.

I removed the alternate address from the properties of the users AD account.

The NDR email is still being received along with every incoming email

Any ideas how I can resolve this?

Thanks

The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.

If I send a mail to the user - user@domain1.com, it appears to be trying to forward it onto user@domain2.com and because this address doesnt exist, that appears to be why I'm getting the NDR.

I cant see any forwarding anywhere under the users profile in the Active Directory - can anyone help???

Thanks

Anyone????

 

[niallo32]

All mail being received by the user is being forwarded to user@domain2.com, an email address for the users corresponding account on a different domain within the same Subnet.

There is no apparant forwarding in place on either Account, under AD properites.

Can anyone shed any light??

Do you have a recipient policy for domain2 on your exchange server ?

Under Default Policies/Properties/Email Addresses. there is an entry for that Domain, with a checkmark next to it.

Only one user is being affected though...
