There are a couple of reasons for this... First, check to see if the user on the computer is authorized, via Active Directory, to send mail. The second thing to check would be the permission that are set for connections in exchange. I believe that there is a setting/permission to allow/deny mail from clients. You should be able to set these by IP range.

So is it an Active Directory error or an exchange error? Do you have an error number or the exact error from the event logs?

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<server.domain.com #5.5.0 smtp;550-5.7.1 [72.26.170.000] The IP you're using to send email is not authorized >

It is an exchange issue. You SMTP IP range is off. Do you have an internal mail server and a DMZ one or just one server for the company?

yes it's an internal mail server, I'm not behind a DMZ, but I made some changes to ma ISA server , not sure if that is causing it,.....so I just allowed all traffic from the mail server an that didnt solve it either, and I dont suspect that it's the ISA causing this error
