I've been researching an issue where emails are getting rejected with these NDR errors:
An error occurred while trying to deliver this message to the recipient's e-mail address. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.
The following organization rejected your message: smoothwall.
Sent by Microsoft Exchange Server 2007
Diagnostic information for administrators:

If I'm reading this correctly the emails are being rejected cause the multi.susrbl.org found a reference to w3.org in a HTML email??
How can this be fixed/removed/corrected?
Thanks, Duane
www.w3.org is not blacklisted. You can confirm this on the lookup page:
The most likely reason for this is DNS corruption:

Please let your recipient's mail administrator know about this, and please let us know how/that they correct it.
