Ok, I have seen so many people with this same problem, but i can not use their fixes to fix my problem. My network has 2003 server, and exchange 2003. I have a smtp virtual server configured with access anonymous access selected, with basic and TLS encription, i also have window intergrated auth. no certifcates, connection is allow only our domain name, and our subnet, relay restrictions is allow only our domain name, and our ip address subnet. I also have let authencated computer use relay checked. For outbound i have anonymous as well. I also comfigured a connector to use SBC.com as my forwarding smart host. I had also tried using dns to find it. Still no emails going to a specific domain. It does work for a message or two, then right back where i began. Here is the error message.
our message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

      'Name Name' on 6/20/2006 11:43 AM
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <Name.name.com #5.7.1 smtp;550 5.7.1 <name@name.com>... Relaying denied. Proper authentication required.>
I really have no clue what to do next.
Any help would be great.
