Hi, I think I have something wrong with my exchange 2007. I tried to send an email to domain 'fgt@hjkilohyuj.com'. This domain does not exist, but when I go to my exchange queue, the email was gone. I used the Microsoft Exchange troubleshooting, and I see that the recipient status is "554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain". I do not receive any NDR and I can not see it the queue. I run the command Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient postmaster@mydomain.com. I log in to the webmail with the postmaster user, this user received the Undeliverable email. If I would that my user received this email, how you do that? If I send an email and I did a mistale on the domain, I will never be notified? Thanks for your help David
