I have one domain on an exchange 2000 server, and everytime they try to email my address which is kdrerup@adsnetcurve.com, they get the following error<br />
<br />
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.<br />
&nbsp; &lt;adsprospect01.adsprospect<wbr />.com #5.5.0 smtp;572 ttyler@ebspartners.com host name is unknown&gt; <br />
<br />
Now what is confusing to me is, which host name is unknown, adsnetcurve.com or ebspartners.com. &nbsp;What is also strange is that I have other users on this server with email addresses different than ebspartners and they do not have any problems.<br />
<br />
Any help would be appreciated.<br />
<br />
Thanks
