Paul,,
I seem to remember Hotmail having issues with this type of mechanism.. You may want to do a search on "Hotmail Violating RFC"S" or something to that effect to verify this. Have fun ErIc ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Weier, Paul Sent: Thursday, October 25, 2007 11:28 AM To: nanog@merit.edu Subject: Hotmail/MSN postmaster contacts? Any Hotmail/MSN/Live postmasters around? My company sends subscription-based news emails -- which go to thousands of users within Hotmail/MSN/Live. I appear to be getting blocked recently after years of success. I have read the postmaster doco at MSN. I have put SPFs for SenderID into many of my news station domains but it doesn't seem to be affecting my success at delivery over other domains which do not yet have any such configs. What am I missing to get un"blacklisted"? I can't seem to find any human contact info on there. Any offline contact would be greatly appreciated. Apologies for the noise. ---------------------------------------------------------------------- Paul Weier [EMAIL PROTECTED]
