Hi! In my mail server logs, I notice for weeks attemps of 40.92.6x.xx IPs (outbound.protection.outlook.com) to deliver mails for the facebookmail.com domain despite that these Microsoft IPs are not listed in the SPF record of facebookmail.com.
A report of the problem to the Microsoft CERT a week ago remained unanswered and without any other reaction. Some examples: 1 Mar 16 09:51:21 frodo postfix/policy-spf[7616]: Policy action=550 Please see http://www.openspf.net/Why?s=mfrom;id=update%2Bzj4o9%3Dzsy6t9%40facebookmail.com;ip=40.92.66.106;r=frodo.akxnet.de 1 Mar 16 15:12:55 frodo postfix/policy-spf[14982]: Policy action=550 Please see http://www.openspf.net/Why?s=mfrom;id=notification%2Bzj4o9%3Dzsy6t9%40facebookmail.com;ip=40.92.69.92;r=frodo.akxnet.de 1 Mar 16 09:42:08 frodo postfix/policy-spf[6563]: Policy action=550 Please see http://www.openspf.net/Why?s=mfrom;id=notification%2Bzj4o9%3Dzsy6t9%40facebookmail.com;ip=40.92.65.65;r=frodo.akxnet.de Does anyone else has that problem? And if yes, is there any other way to get Microsoft aware of that and stop those attempts?
