We have installed SBS 2003 with Exchange 2003 and we are pulling our email off from our isp's mail server with the microsoft pop connector. We are not able to send our internal email to external email like yahoo, hotmail, gmail, etc. I have searched for instructions from many articles but nothing is working for me. Below is the error that I am getting:
There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator. <mycompany.com #5.5.0 smtp;550 relaying mail to gmx.com is not allowed>

Any ideas how to fix this? Thanks
