used to host user@abc.com, cant email them since we stopped hosting

[paulha]

Morning all.

We used to host abc.com on our exchange server. All abc.com users had accounts in our active directory, their email addresses were configured as user1@abc.com, user2@abc.com etc.

Recently abc.com decided to stop using us to host their email. I deleted the recipient policy in esm that applied to abc.com, deleted the forward lookup in our DNS, and deleted the email smtp address user1@abc.com etc from their Active directory accounts.

I can email them successfully from hotmail.com, but when I email them from our domain, I get a pretty rapid undeliverable, suggesting that it is still routing internally some how.

Has anybody got any idea on what I have forgotten to do ?

Thanks in advance

Paul

What is the exact NDR? Have you flushed the DNS cache?

It is now working, I havent been anywhere near it for 24 hours, must have been a replication problem I guess

Thanks anyway
