help needed

[I . Herman]

I am getting the following all of a sudden.  My control files all have that 
domain in them.

Here is what I'm getting.  This is a normal user account.

<[EMAIL PROTECTED]>:
x.x.x.x does not like recipient.
Remote host said: 554 <[EMAIL PROTECTED]>: Recipient address 
rejected: Relay access denied
Giving up on x.x.x.x.
