Hi, since several weeks I see more and more SPF-Errors for mails coming from O365. It seems that when mails gets relayed, they use outbound mail servers that are not valid for sending from the (relaying, not origin) mail address.
My O365 account where I have relaying active is an academic account. The last failure comes from IP 40.95.92.45 and is trying to deliver mails from klaus_eth...@stud.phzh.ch (my academic account). > spfquery -ip 40.95.92.45 -sender klaus_eth...@stud.phzh.ch fail Please see http://www.openspf.org/Why?id=klaus_ethgen%40stud.phzh.ch&ip=40.95.92.45&receiver=spfquery : Reason: mechanism spfquery: domain of stud.phzh.ch does not designate 40.95.92.45 as permitted sender Received-SPF: fail (spfquery: domain of stud.phzh.ch does not designate 40.95.92.45 as permitted sender) client-ip=40.95.92.45; envelope-from=klaus_eth...@stud.phzh.ch; It is pretty impudent from microsoft to write in the deliver failure: It's likely that only the recipient's email admin can fix the problem. Unfortunately, it's unlikely Office 365 Support will be able to help with these kinds of externally reported errors. No, it IS solely the fault of Microsoft not be able to manage SMTP correctly. Any ways to get them to correct their SMTP setup? Regards Klaus Ps. Could it be, that http://www.openspf.org/Why is broken? I get connection refused. -- Klaus Ethgen http://www.ethgen.ch/ pub 4096R/4E20AF1C 2011-05-16 Klaus Ethgen <kl...@ethgen.ch> Fingerprint: 85D4 CA42 952C 949B 1753 62B3 79D0 B06F 4E20 AF1C
