I removed the name server software version information from our DNS servers and also upgraded them at the same time.
The SOA serial number will be modified to use the YYYYMMDDnn syntax in our next software update.
A postmaster@ account has been added.
WWW has always been enabled. I'm not sure why the report shows that they were unable to connect.
The SMTP greeting, and Open Relay test were from the McAfee MX Logic anti-spam servers which unfortunately I have no control over.
Thanks for you help.
