Have just installed Small Business Server 2008 x64, with clients using XP Pro SP3 with all the updates. Prior to the installation there was no issues sending or receiving mail with their old Server 2000/ Exchange 2003.

Reject messages from no senders is also not checked.

FYI clients are also getting this other bounceback which i am also going to log. Info at the bottom:


Please advise

Answer : Your message wasn't delivered because of security policies. Microsoft Exchange will not try to redeliver this message for you. Please provide the following diagnostic text to your system administrator

The #554 5.7.1 error usually indicates either a virus found or a spam or content filter rejection. "TEST" in subject is one content filter that causes rejection.

The #550-Bad hostname indicates the server may not be properly registered.  Check your DNS records to be sure the server host name (FQDN) and IP address is correct.
