smtp;550 sorry, your HELO/EHLO greeting is not RFC2821 compliant (#5.7.1)

I have installed Exchange Server 2003 on a computer. The Exchange server is working nice, but I got one error message when I try to send to one domain;
smtp;550 sorry, your HELO/EHLO greeting is not RFC2821 compliant (#5.7.1).
In System Manager I have tried to change the server to send HELO insted of EHLO (System Manager - Connectors - Small Bussiness SMTP Connector - Properties - Advanced - Send HELO insted of EHLO). The server has been restarted, but still I get the same error message. What can I do?
All other domains are working properly.
The server is a Small Business Server 2003 with all Service Packs and patches installed.
