Your message below was rated an SCL of 3 by my IMF. I see most list messages rated less than 5. All things being equal, all IMF's should report the same SCL for a given message. So all things are NOT equal. SCL rating is influenced by SPF results. Have you properly configured your Perimeter IP list and Internal IP Range? As I told you in October 2005: "Perimeter IP list/range are the IPs of machines delivering inbound mail to you which will not be checked for SenderID compliance. You could also think of this as a "whitelist"." Your internal networks, and the IP of any machines outside your network which routinely forward or originate mail to your Exchange server, should have their IP addresses listed there. You can view SPF results for individual messages in Outlook: http://searchexchange.techtarget.com/tip/1,289483,sid43_gci1144172,00.html?b ucket=ETA Carl _____ From: Andrew English [mailto:andrew@xxxxxxxxxxxxxxxxxxxxxx] Sent: Sunday, January 08, 2006 10:09 PM To: [ExchangeList] Subject: [exchangelist] IMF uhm... I have been noticing that some of the [exchangelist] messages are getting a SCL rating of 7 and 8 and are being archived (rejected), however I am constantly getting emails from these OEM software pirates that aren't being filtered at all. Odd. Andrew
