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

Do you have any non-alphanumeric characters in your servername, besides periods?

Hi!
Thanks for quick reply!
Amaheshwari: Since we want to wash our e-mail for spam and viruses before it reach the server, the MX record for the domain is pointing to a ISP. The ISP will forward the e-mail to our server when the scanning process is completed. Therefore I get answer from the ISP email server when I check the domain... Do you know other tools I can use to check this, where I can use IP adress?
LeeDerbyshire: The servername is: xxxxx-xxx.
Thanks!

Since your MX records are pointing to your ISP, do you know if your outgoing messages are also being relayed through your ISP? Do you have them configured as your smart host? The problem might be with your ISPs server name - although you would expect them to know about things like this.
RFC2821 means reverse lookup issue
550 Sender Domain must exist
eg:
550-EarthLink does not recognize your computer (10.0.0.10) as connecting from an EarthLink connection
http://support.microsoft.com/?kbid=284204
If you do not have a good DNS server locally use a external one from the isp and create a Smart host.

Doh... I changed the FQDN from domain.com to mail.domain.com. domain.com point to my ISP, and mail.domain.com point to the server...
Thanks for all help!!! Great!
