Mail receiving problem

I just create an email with standard integrated interface, it`s working now, all okay for sending, but I cannot receive some of mails, from Yahoo and Hotmail for example. None of filters were turned. Error that I receive in yahoo was:
Remote host said: 554 5.7.1 : Recipient address rejected: Access denied [RCPT_TO]

After that I send mail to the second accaunt and now receive:
Remote host said: 550 5.1.1 : Recipient address rejected: User unknown in virtual alias table [RCPT_TO]

Thanks in advance for your help.

I am having a similar issue. I can send mail out from my created email address from dreamhosts webmail interface, but I can not receive any emails.

Did you get this resolved?
