From: Alex on 21 Apr 2010 14:34 Is there a bug in the sender ID or am I missing something: Why is there a failure on: Test-SenderId -IPAddress 195.90.96.17 -PurportedResponsibleDomain icomm.co.uk I checked the spf records for that domain: icomm.co.uk: v=spf1 mx ptr mx:mail.probrand.co.uk mx:mail2.probrand.co.uk mx:mail3.probrand.co.uk ip4:195.188.200.0/25 ip4:62.49.129.106 include:spf.maildefender.net -all spf.maildefender.net: v=spf1 ip4:195.90.96.0/23 ip4:91.192.232.0/24 ip4:212.50.178.128/26 -all i.e. there should be a pass becasue of the entry "ip4:195.90.96.0/23" ???? Is this a bug? Regards, Alex

Whether it's a bug only MS can tell. It certainly doesn't seem to be correct. Testing the IP address and domain here (http://www.kitterman.com/spf/validate.html) produces a "Pass" result. --- Rich Matheisen MCSE+I, Exchange MVP
