Problem sending email

[VB Programmer]

I'm encountering an error whenever I try to email people not in my domain.

I get this error:

The server rejected one or more recipient addresses. The server response
was: 550 You must check your mail from this IP or SMTP Auth before sending
to (e-mail address removed)

Here's the full error:

System.Web.HttpException: Could not access 'CDO.Message' object. --->
System.Reflection.TargetInvocationException: Exception has been thrown by
the target of an invocation. --->
System.Runtime.InteropServices.COMException (0x8004020F): The server

Any ideas?
