I've setup an email account for a mirrored Domain name using the web-based panel. Everything seems okay, and it's suppose to goto the Ruble Server inbox, however, the mail is getting sent to Decker, and I'm getting an 'Undeliverable Mail' Error message as follows:
This is the Postfix program at host decker.dreamhost.com.
I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.
For further assistance, please send mail to <postmaster>
If you do so, please include this problem report. You can
delete your own text from the message returned below.
The Postfix program
<USERNAME@decker.dreamhost.com>: unknown user: "USERNAME"
Any assistance in fixing this would be greatly appreciated!
